Investigating the Properties of Ph

Exploring the Properties of pH The manufacture’s guarantee is that Sensodyne toothpaste smaller scale solidifies tooth lacquer to help secure against the impacts of corrosive wear, helps prevent the twinges of agony from touchy teeth planned with low abrasivity, unbiased pH and delicate yet powerful cleaning framework. To see whether the makes guarantee on Sensodyne toothpaste is the right degree of pH. I anticipate that the Sensodyne toothpaste should be an impartial pH level as the fabricates guarantee that this items pH level is nonpartisan. This would be shown by a degree of pH 6 and 7. The hardware required for this commonsense * Sensodyne (toothpaste) Universal pointer * Universal paper * pH meter * Petri dish x 3 * Measuring chamber x 6 * Wooden stick * Distilled water * Tap water * Ruler Method 1. Test the refined water and faucet water for the pH level to check whether it were impartial so it wouldn’t have any kind of effect to the outcomes. 2. Set up 3 petri d ishes and 3 estimating chambers 3. Measure 10mls of faucet water. Add water to the petri dish and include 5cm of Sensodyne (toothpaste) into each petri dish and rehash this stage multiple times. 4. Measure 10mls of refined water and add to the estimating chambers just as including 5cm of Sensodyne (toothpaste) and rehash this stage multiple times. . Combine the substances with the wooden stick. 6. Put widespread pointer (fluid) into the petri dish rehash this stage multiple times. Record the outcomes from each petri dish. 7. Put general marker (paper) into the estimating chamber rehash this stage multiple times Record the outcomes from each estimating chamber. 8. Set up pH meter, Put the pH meter into the estimating chamber record the pH perusing and rehash this stage multiple times for a dependable. Results Table Universal Indicator Universal Paper pH Meter Test 1 pH6 6 7. 0 Test 2 pH6 6. 99 Test 3 pH6 6 7. 09 Photographic proof of examinations Before: After: Before: After: Discuss ion * The outcomes show pH of the toothpaste is nonpartisan as indicated by the pH meter, and marginally acidic as per the paper and pointer. The pH was found to be somewhere in the range of 6 and 7 in all the tests done * The manufacturers’ guarantee was the pH level of the sensodyne (toothpaste) was unbiased. My speculation was that the toothpaste was pH nonpartisan and this was bolstered by the outcomes. * I thought about refined water and faucet water in light of the various synthetics blended in with the water, yet the outcomes indicated no distinction so it didn’t influence the pH. The pH meter indicated small changing however not all that much this could be that the pH meter is out or that there could be a major issue with the meter in light of the fact that with my bolstered proof its probably not going to not be right. To improve this trial is test with more than one pH meter to check whether there’s a distinction in examination. Else it might be increasingly proficient if there were more tests accomplished for more help towards the outcome. * My autonomous variable is the sensodyne (toothpaste) in light of the fact that in each analysis I utilized a similar measure of sensodyne. The dependant variable was the pH levels were I didn't have authority over what the pH level would demonstrate. This is the explanation the outcomes are dependable on the grounds that I rehashed the means multiple times in each test and kept on getting similar outcomes. This analysis could be improved by getting tests of toothpaste from an assortment of areas. This will distinguish and inconsistency’s in the item itself. End * The test found that the makes guarantee of pH is right and it is an unbiased pH with upheld proof. Teeth would be influenced by acidic toothpaste or soluble toothpaste. In this way a pH somewhere in the range of 6 and 7 is a fitting toothpaste . This sensodyne (toothpaste) is intended to help individuals with touchy teeth.

Democracy1 Essay Example For Students

Democracy1 Essay Vote based system by sheer definition is equal with balance. Along these lines, the idea of mainstreaming fits consummately in this situation. Majority rules system originates from the Latin word demos meaning the individuals, one kind of individuals, however all individuals. Mainstreaming kids with handicaps into general classes ought not be a benefit, yet a typical thing. Doing this thusly would ingrain a feeling of acknowledgment and resistance in the understudies, in this way decreasing the measure of separation that an exceptional instructive understudy may be presented to in future years. Majority rule government is alive and functioning admirably in the state funded educational system. It is called mainstreaming. The government funded educational system has an obligation to give equivalent chances to all understudies. By a similar token, mainstreaming permits that benefit to be reached out to the kids with incapacities. Mainstreaming is an expansion of the possibility of vote based system in schools. Mainstreaming is the training that permits incapacitated kids the most proper and compelling instructive encounters, which will empower them to become confident grown-ups. By presenting understudies to youngsters with inabilities, other kids see that nobody is extraordinary or ought to be dealt with distinctively because of shallow conditions. Consequently, considering debilitated youngsters to get treated similarly and decently. This would impart a sentiment of self-esteem and lift self-assurance. Mainstreaming fortifies the estimations of persistence, resistance, and disheartens separation. Additionally, by mainstreaming, a sign is conveyed saying that all individuals are deserving of similar instruction and chances paying little mind to shading, doctrine, or ability. It is assessed that around 3% or 6.5 million people in the U.S. has mental impediment and Drew et al., 1996 feels that the organizations ought to be finished off to the individuals with hindrance being come back to the network and home conditions. At first mainstreaming was planned for understudies with gentle handicaps. An increasingly present development tries to furnish youngsters wi th moderate to extreme handicaps with comparable chances. Open Law 94-142, the Education for All Handicapped Children Act of 1975 was authorized and denoted the start of another period for students of exceptional needs. In 1990 this was altered and renamed the Individuals with Disabilities Act (IDEA) and incorporated the crippled between the ages of 3 and 21 (Gollinick, 178-179). This law offers states monetary help to make a free and proper government funded instruction accessible to each kid with incapacities at no expense to the parent. The experts job isn't to mention to the families what choices to make, however to prompt them on how best to make it-to give insight, data, and bolster where they are required (Meisel, 8). The nearby training position (LEA) do as well as can be expected to meet the custom curriculum needs (SENs) of youngsters inside the restrictions of their comprehension of those requirements and the financial plan accessible. Lawmakers make the SEN strategy, nonetheless, the LEA can not make proposals that will at last cost cash they can not manage (Hall, 227). The law is evident that the LEA must serve a duplicate of the proposed proclamation inside about fourteen days of the date on which the evaluation of the SEN understudy was practiced. This should be reasonable and clear to the parent. A case of how the LEA gets around this as to cost is as per the following (Hall, 247):Actual needTammy has the requirement for consistent one-to-onesupport for all exercises all through the school day on the grounds that without this nothing canStated provision:Flexible staffing levels to address her issues at anyIn reality, Tammy spent between 50-60 percent of her day trusting that someone will accomplish something for or with her since she had no methods for correspondence and no deliberate development and was absolutely visually impaired. Without a devoted help laborer, a lot of her day was squandered simply pausing. It is, in this manner, clear that the LEA has all the earmarks of being making arrangements which may never emerge. This leaves the SEN understudy and guardians disappointed and furious. Guardians reserve a privilege to bid against the choice of their LEA to a free Tribunal. On the off chance that an understudy isn't getting the assistance she/he needs, mainstreaming will be progressively troublesome. The IDEA was passed by Congress to guarantee that all kids with incapacities get a free, proper, government funded instruction, which underscores custom curriculum, and related administrations intended to meet their extraordinary needs. Right now, schools across the nation serve about 6% of understudies who are intellectually hindered in fundamentally customary study halls. An extra 20% are getting administrations from an asset study hall (where the understudy invests energy learning in a customary homeroom and afterward to a different exceptional study hall). 72% of intellectually hindered youngsters are as of now instructed in prohibitive settings. A huge part of these understudies are instructed in discrete homerooms while 10% despite everything get training in isolated schools (http://www.thearc.org/). Fruitful mainstreaming is particularly subject to inspirational perspectives by standard homeroom instructors (RCTs). Levels of acknowledgment of incapacitated kids by RCTs have been debilitating. A study of 200 instructors uncovered that lone 38% bolstered the idea of mainstreaming. Of that percent just 40.5% were happy to acknowledge the somewhat disabled individual in their homerooms (Meisel, 119). It is when impaired understudies are preferred, acknowledged, and picked as companions that mainstreaming turns into a positive impact on the lives of both debilitated and non disabled understudies. Likewise giving incapacitated understudies access to and productive association with non debilitated friends. Mainstreaming isn't something to accomplish for a couple of understudies, yet, rather, something to accomplish for all understudies. This could possibly work out. On the off chance that non-impeded understudies dismiss the disabled, there might be expanded preference (Reynolds, 26). Just a not many youngsters should be instructed in some different option from the standard school condition: Boys and young ladies whose life/wellbeing circumstances is delicate to the point that moving them from habitation to somewhere else for tutoring would imperil their lives. Mainstreaming has to do with instructing kids for all or part of the school day in the ordinary study hall with the customary educational program, with understudies who have not been named handicapped.Some feel that mainstreaming implies returning youngsters to standard homerooms, be that as it may, the primary idea isn't returning kids; yet rather not expelling kids in any case (Reynolds, 54). I intend to show grade school and take an individual view and obligation in taking care of this issue of isolation or combination. Is it savvier to isolate students of various degrees of capacity or to incorporate them? A significant contention for isolated arrangement is that the debilitated understudies are increasingly positive and have more prominent confidence when set with other impeded understudies. Then again, reconciliation gives the impaired kid a chance to show non-disabled friends and be spurred to mirror the conduct of these higher performing peers.I emphatically concur that the schools should play a progressively dynamic job in organizing their study halls to suit the custom curriculum needs of understudies. These understudies ought not be marked and isolated, they ought to be coordinated and have similar open doors for learning and turning into a piece of the standard. Fundamentally, all schools ought to be focused on esteeming understudies of numerous types and remember them for all parts of school life paying little mind to the marks set on them. An instructors work is to assist understudies with defining sensible objectives and recognize which educational program and guidance ought to be outfitted to meet those objectives. Mainstreaming surely accompanies its advantages yet the best spot to support these kids set significant objectives and learn important abilities to work effectively, as future grown-ups would be the network in general. Remembering custom curriculum understudies for normal study halls keeps them in the standard of instruction. Their assignments can be constrained and they can get supplemental guidance for material they experience issues appreciating. As far as majority rule government they have the chance to get similar training as every other understudy and by not expelling them from customary instruction, they are not being dealt with in an unexpected way. A few people see pull out an inconvenient to these children and others consider it to be a unique treatment for them. Specialized curriculum kids offers a ton to ordinary study halls. It is accepted by some that children need to learn of contrasts and resilience early. As far as understudies with learning handicaps since they experience issues perusing the course book, doesnt mean they won't get familiar with the material through talk, ventures, and so forth. For the most part, if the understudy is sufficiently certain, they can stay aware of th e remainder of the class with adjustments made to understanding material, assignments and tests. By remembering them for the normal ed classes there is value in their training and decent variety in the number of inhabitants in the study hall. Throughout the late spring of 1998, I filled in as a camp advocate at the Kendall Boys and Girls Club. This camp acknowledges all kids whether they are white, dark, Hispanic, or have a handicap. During that time at camp, I got connected to a young man named Marty. Marty was one of the alleged exceptional children since he was hard of hearing. Consistently, Marty and I turned out to be close and I got an opportunity to meet his family. I would converse with them about his condition and get some information about his tutoring. I recently expected that Marty went to an extraordinary school, yet that was not the situation. Marty is being mainstreamed into a typical school. I asked his mom how well he was doing and if there were any issues. She stated, he is doing alright in school, battles somewhat, yet then what kid doesnt. She let me know toward the starting that Marty was having social issues with different kids. He wasnt fitting in and

Intestate Succession Act Business Law

Question: Talk about the Intestate Succession Act for Business Law. Answer: 1. Circulation of Residuary Estate A residuary statement is a condition that gives property that is left by the expired. The proviso is contained in a will and might be available in a will after all the property has been granted to the legitimate recipients in the will and what is remaining isn't explicitly arranged by the given will, is what is accommodated in the condition. The property that is being handed down in a residuary provision is ordinarily alluded to as the residuary home. The expired, Mr. Alvin, has passed on yet has not left any enduring life partner and along these lines rule 2 of area 7 Intestate Succession Act( 1967) won't make a difference. In any case, it is enthusiasm to take note of that there are two enduring god kids that have been left and along these lines Rule 3 of the demonstration will apply here where the domain of the expires that isn't dispersed in this sense will be separated in equivalent measure between the youngsters and the some other legitimate agents of the kids. The wording of area 7 standard 3 has obviously characterized the lawful agents of the kids as their relatives and ignored any closest relatives. It ought to likewise be noticed that the god kids however are not the natural offspring of the perished, they have been coverd by law as offspring of the expired inside the meaning of area 3 of the Intestate Succession Act ( 1967). The legitimate represeantives that have been alluded to for this situation incorporate Elvin Tan, Jim Tan and David Tan who will likewise have an equivalent offer in the leftover property of the perished. Anyway it has been noted in the realities of the case that Elvin has died and has been left with an enduring life partner and two kids Fin and Han. For this situation Rule 2 segment 7 of the Intestate Succession Act will apply and the spouse to Elvin will be qualified for half of the lingering share that should have been given to Elvin by ethicalness of Rule 3 of the Act and the other half will be to the kids. It is of specific hugeness to take note of that Han and Fin are minors since Han is five years of age and Fin is seven years of age. As rule three has noticed, the youngsters will be spoken to by their quick lawful delegate who for this situation will be the mother of the kids. Jim tan and David Tan are the main enduring kin and relative of Alvin. As has been noted above Jim and tan will be qualified for the residuary domain however they will each take an equivalent elixir. Basically, the lingering bequest will be isolated among four individuals. The two god youngsters that have been left by the perished and the 3 kin left by Alvin anyway the offer that is to go to the expired kin will be given to the family as per the guidelines clarified previously. 2. Sorts of inheritances in provision 2 and 3 The sort inheritances have been expansively talked about on account of Celantano Estate v Ross (2014) and the guidelines that have been built up will be applied in the conversation hereunder. Provision 2 The kind of heritage that is in statement to can be depicted as an expressive inheritance as it will prove underneath. An expressive inheritance has been said to contain both of the e components of a general heritage and a particular inheritance. As it were it is viewed as a particular inheritance since its wording indicates the specific or rather the particular sum or thing that will be given to a specific explicit individual referenced by the expired. Anyway what makes it mostly a general inheritance is the way that the predefined measure of cash can be brought from the general lingering sum that has been left by the expired. An expressive inheritance has been shown on account of Wood Estate v. Arlotti-Wood (2004) in section 12 of woods state where the proviso expressed that I give [pounds] 100 to be raised out of the offer of my Surrey properties. For this situation the statement 2, since it is explicit with respect to the sum which is $5000 it very well may be contended that it i s an expressive heritage. The provision will likewise have the option to produce results in light of the fact that the aggregate of cash may originate from any of the piece of the perished domain. Statement 3 A particular inheritance is that is explicitly makes reference to in the will from which part of the bequest the cash or some other thing will be found from (Halsburys Laws of England 1998). The inheritance in condition three which was to Simon Temper the godson of the perished can been supposed to be a particular heritage on the grounds that the measure of cash that was handed down was determined structure a specific explicit piece of the expired bequest which is OCBC Bank account number 485772. It very well may be recognized from the above decisive heritage by the way that in the definite inheritance there has been no particular notice of which financial balance or part of the bequest of the expired the cash to be given to his companions will originate from. The main recognizable ledger for this situation is DBS Bank Account. Due to examples, for example, this the courts have consistently avoided deciding that a specific provision uncertainties explicit except if the statement is c learly one and has been explicitly satisfied in the will in clear words that it is explicit as was noted on account of Smith Estate (Re) (2003). The courts have likewise chosen in Re Culbertson that the strict and standard significance ought to be translated out of the wording in the proviso to figure out which sort of inheritance the statement could be suggesting. At the point when statement 3 is deciphered in its strict significance it can clearly be perceived that it is a particular inheritance. It very well may be seen from the realities of the case that Late Mr. Ivan had no any financial balance with OCBC ledger and in this manner the heritage won't have the option to produce results. 3. An award of letters of organization with will added (cum confirmation added ) is normally given where the agent of the property of the expired isn't there to direct the property of the perished .The agent may not be available on the grounds that they additionally passed on after the will was made. Furthermore the award of the letter of organization with will attached is regularly made where the expired kicked the bucket testate and there was a legitimate will and however there is additionally a leftover property of the perished that has not been doubted in the will. Fundamentally the perished is held to have passed on mostly testate and incompletely intestate that is the reason the will is appended exactly award of organization. Regularly when an individual bites the dust testate having deserted a will the sort of award of portrayal that will be caused will to be the award of probate. For our situation in point it very well may be seen that the individuals who were designated as agents of the will for this situation have kicked the bucket. Furthermore, it has additionally been noticed that the domain of Late Mr. Alvin has not been altogether granted as there is a lingering home that has been. It in this manner follows that the suitable award of portrayal for this situation will be the award of letters of organization with will added. Since all the agent have passed on for this situation the standard that explains who will have the option to apply for the award will be appropriate according to Probate and Administration Act(Chapter 251). The demonstrations in segment 13 provides the request for need on who will have the option to apply for the award of letter of organization with the will attached. Agreeing the request given is area 13 the residuary legatee of any general legatee that has ben accommodated in the will is qualified for apply for the award of the letters of organization with the will added. For this situation the goddaughter of the expired is a leftover legatee being a lawful offspring of the perished and having been given in rule 3 of segment 7 Intestate Succession Act ( 1967), she can apply for the letters of organization in the event that she achieves the age of 18. Moreover, the two siblings that have been left by the expired who are the organic siblings are additionally inside the meaning of lef tover legatees as gave fro in the previously mentioned segment, and they may likewise apply fro the letters of organization with the will added. The application for the award must indicate that the candidates are of the imperative mental limit inside the meaning of Mental Capacity Act (Cap. 177) (Subordinate Courts of the Republic of Singapore Practice Directions Amendment No. 1 of 2012). It ought to likewise be borne as a top priority that by dint of area 55(1) of the Probate Act the where no application for the award has been made inside a half year the letters of organization with the will attached might be allowed to the open trustee by the court (Chiang Shirley v Chiang Dong Pheng 2015). 4. The god little girl for this situation has been granted $5000 given that she arrives at 18 years of age. It very well may be seen that there is a predefined measure of cash that has been granted for this situation in spite of the fact that the particular wellspring of the cash from the home of the expired has not been determined. By applying the decision that was oversee on account of Re Culbertson (1967) that the wording of a statement ought to be given a conventional plain significance. It tends to be presumed that the condition isn't a determine heritage in the severe sense since it doesn't indicate the wellspring of the domain that the measure of cash ought to be taken from. Nonetheless, it could be viewed as a general inheritance in light of the fact that the measure of cash that will be paid may originate from any wellspring of the deceaseds domain. Basically, on account of the way that the inheritance is torn in the middle of the general heritage and the extraordinary inheritance, it tends to be surrendered that the sort heritage for this situation is he expressive heritage. The inheritance will produce results on the grounds that the measure of cash can be brought from a wide wellspring of the domain of the perished however just with the condition that until she accomplishes the age of 18 years.

2 things you should review prior to selecting your dream school COLUMBIA UNIVERSITY - SIPA Admissions Blog

2 things you should review prior to selecting your dream school COLUMBIA UNIVERSITY - SIPA Admissions Blog Congratulations, you’ve been accepted to SIPA! But you have too many offers, and it’s hard to decide. I know many of you are in these shoes so this post is meant to help you decide (and not sway you). To make an informed decision, key elements of the issue must be considered. Two of them will be discussed here: tuition and living costs and relevant employment opportunities. For tuition and living costs, you’re right. SIPA is up there on the list when it comes to pricey graduate programs, and you pay for what you get. Aside from information you already know (Ivy League prestige with world-class faculty and a campus in one of the greatest cities in the world), you really need to ask yourself if you want to “cheap out” on an investment toward your life. But other programs awarded funding or more funding than SIPA? Consider that dilemma, and ask yourself how significant that number is. It’s one thing to get $10,000 over two years than, say, $80,000 in the same period. In other words, how much will it take for you to give up your dream school? On that note, if you need some extra help strategizing how youll pay for graduate school, join us for the  Financial Planning for Your Graduate Education Webinar on March 29 at 10:00 a.m. EST. You can RSVP here. On relevant employment as a student, you’re probably thinking of paid/non-paid internships in a field where you’ll likely end up. This would be the disadvantage of choosing SIPA if DC is the target (although only to a slight degree). If you’re stuck on this point, you should take an honest look at what you want to get out of graduate school (in the near term). Is it building that academic/theoretical foundation and overloading on coursework, immersing yourself in student life and building meaningful relationships, and/or gaining valuable work experience? If you’re thinking all the above, you must hate sleeping. For some people, going back to school is meant to be a break from professional life. If building experience is a priority, you should consider how much the pay (if any), and exactly how substantive the work will be when going in part-time. Don’t forget about the mind capacity you’ll need for the time-consuming econ/quant problem sets waiting for you afterward. And if youre looking for additional insights into where SIPA students work, our Career Services tells you that and more here.  For example, roughly one-third of 2016 graduates  joined the public sector after graduation. I had considerable work experience and clear goals coming into SIPA. Believe me, I love having money in my pocket, but going to my dream school mattered more. my biggest fear in life is living with regret. Besides, if I was going into debt regardless, I’d rather do it for something I most wanted. Developing an academic foundation and establishing a tight network were my goals for graduate  school. In the end, the decision was easy. Good luck and congratulations again! [Photo courtesy of  Garrett Coakley  |  (CC BY-NC 2.0)]

Anatomy And Physiology Of Ckd - Free Essay Example

ANATOMY AND PHYSIOLOGY Chronic Kidney Disease Cardiovascular System The cardiovascular system is sometimes called the circulatory system. It consists of the heart, which is a muscular pumping device, and a closed system of vessels called arteries, veins, and capillaries. As the name implies, blood contained in the circulatory system is pumped by the heart around a closed circuit of vessels as it passes again and again through the various circulations of the body. The Heart * The heart is enclosed by a sac known as the pericardium. There are three layers of tissues that form the heart wall. The outer layer of the heart wall is the epicardium, the middle layer is the myocardium, and the inner layer is the endocardium. The internal cavity of the heart is divided into four chambers: * Right atrium * Right ventricle * Left atrium * Left ventricle * The two atria are thin-walled chambers that receive blood from the veins. The two ventricles are thick-walled chambers that forcefully pump blood out of the heart. Differences in thickness of the heart chamber walls are due to variations in the amount of myocardium present, which reflects the amount of force each chamber is required to generate. The right atrium receives deoxygenated blood from systemic veins; the left atrium receives oxygenated blood from the pulmonary veins. Valves of the Heart Pumps need a set of valves to keep the fluid flowing in one direction and the heart is no exception. The heart has two types of valves that keep the blood flowing in the correct direction. The valves between the atria and ventricles are called atrioventricular valves (also called cuspid valves), while those at the bases of the large vessels leaving the ventricles are called semilunar valves. The right atrioventricular valve is the tricuspid valve. The left atrioventricular valve is the bicuspid, or mitral, valve. The valve between the right ventricle and pulmonary trunk is the pulmonary semilunar valve. The valve between the left ventricle and the aorta is the aortic semilunar valve. When the ventricles contract, atrioventricular valves close to prevent blood from flowing back into the atria. When the ventricles relax, semilunar valves close to prevent blood from flowing back into the ventricles. Pathway of Blood through the Heart While it is convenient to describe the flow of blood through the right side of the heart and then through the left side, it is important to realize that both atria contract at the same time and both ventricles contract at the same time. The heart works as two pumps, one on the right and one on the left, working simultaneously. Blood flows from the right atrium to the right ventricle, and then is pumped to the lungs to receive oxygen. From the lungs, the blood flows to the left atrium, then to the left ventricle. From there it is pumped to the systemic circulation. Blood Supply to the Myocardium The myocardium of the heart wall is a working muscle that needs a contin uous supply of oxygen and nutrients to function with efficiency. For this reason, cardiac muscle has an extensive network of blood vessels to bring oxygen to the contracting cells and to remove waste products. The right and left coronary arteries, branches of the ascending aorta, supply blood to the walls of the myocardium. After blood passes through the capillaries in the myocardium, it enters a system of cardiac (coronary) veins. Most of the cardiac veins drain into the coronary sinus, which opens into the right atrium. Blood Vessels Blood vessels are the channels or conduits through which blood is distributed to body tissues. The vessels make up two closed systems of tubes that begin and end at the heart. One system, the pulmonary vessels, transports blood from the right ventricle to the lungs and back to the left atrium. The other system, the systemic vessels, carries blood from the left ventricle to the tissues in all parts of the body and then returns the blood to the right atrium. Based on their structure and function, blood vessels are classified as either arteries, capillaries, or veins. Arteries Arteries carry blood away from the heart. Pulmonary arteries transport blood that has a low oxygen content from the right ventricle to the lungs. Systemic arteries transport oxygenated blood from the left ventricle to the body tissues. Blood is pumped from the ventricles into large elastic arteries that branch repeatedly into smaller and smaller arteries until the branching results in microscopic arteries called arterioles. The arterioles play a key role in regulating blood flow into the tissue capillaries. About 10 percent of the total blood volume is in the systemic arterial system at any given time. The wall of an artery consists of three layers. The innermost layer, the tunica intima (or just intima), contains simple squamous epithelium, basement membrane and connective tissues. The epithelium is in direct contact with the blood flow. The middle layer, the tunica media, is primarily smooth muscle and is usually the thickest layer. It not only provides support for the vessel but also changes vessel diameter to regulate blood flow and blood pressure. The outermost layer, which attaches the vessel to the surrounding tissue, is the tunica externa or tunica adventitia. This layer is connective tissue with varying amounts of elastic and collagenous fibers. The connective tissue in this layer is quite dense where it is adjacent to the tunic media, but it changes to loose connective tissue near the periphery of the vesse Veins Veins carry blood toward the heart. After blood passes through the capillaries, it enters the smallest veins, called venules. From the venules, it flows into progressively larger and larger veins until it reaches the heart. In the pulmonary circuit, the pulmonary veins transport blood from the lungs to the left atrium of the heart. This blood has a high oxygen content because it has just been oxygenated in the lungs. Systemic veins transport blood from the body tissue to the right atrium of the heart. This blood has a reduced oxygen content because the oxygen has been used for metabolic activities in the tissue cells. The walls of veins have the same three layers as the arteries. Although all the layers are present, there is less smooth muscle and connective tissue. This makes the walls of veins thinner than those of arteries, which is related to the fact that blood in the veins has less pressure than in the arteries. Because the walls of the veins are thinner and less rigid than arteries, veins can hold more blood. Almost 70 percent of the total blood volume is in the veins at any given time. Medium and large veins have venous valves, similar to the semilunar valves associated with the heart, that help keep the blood flowing toward the heart. Venous valves are especially important in the arms and legs, where they prevent the backflow of blood in response to the pull of gravity . Capillaries Capillaries, the smallest and most numerous of the blood vessels, form the connection between the vessels that carry blood away from the heart (arteries) and the vessels that return blood to the heart (veins). The primary function of capillaries is the exchange of materials between the blood and tissue cells. Capillary distribution varies with the metabolic activity of body tissues. Tissues such as skeletal muscle, liver, and kidney have extensive capillary networks because they are metabolically active and require an abundant supply of oxygen and nutrients. Other tissues, such as connective tissue, have a less abundant supply of capillaries. The epidermis of the skin and the lens and cornea of the eye completely lack a capillary network. About 5 percent of the total blood volume is in the systemic capillaries at any given time. Another 10 percent is in the lungs. Smooth muscle cells in the arterioles where they branch to form capillaries regulate blood flow from the arterioles into the capillaries. Role of the Capillaries In addition to forming the connection between the arteries and veins, capillaries have a vital role in the exchange of gases, nutrients, and metabolic waste products between the blood and the tissue cells. Substances pass through the capillaries wall by diffusion, filtration, and osmosis. Oxygen and carbon dioxide move across the capillary wall by diffusion. Fluid movement across a capillary wall is determined by a combination of hydrostatic and osmotic pressure. The net result of the capillary microcirculation created by hydrostatic and osmotic pressure is that substances leave the blood at one end of the capillary and return at the other end. Urinary System The principal function of the urinary system is to maintain the volume and composition of body fluids within normal limits. One aspect of this function is to rid the body of waste products that accumulate as a result of cellular metabolism. Other aspects of its function include regulating the concentrations of various electrolytes in the body fluids and maintaining normal pH of the blood. In addition to maintaining fluid homeostasis in the body, the urinary system controls red blood cell production by secreting the hormone erythropoietin. The urinary system also plays a role in maintaining normal blood pressure by secreting the enzyme renin. The urinary system consists of the kidneys, ureters, urinary bladder, and urethra. The kidneys form the urine and account for the other functions attributed to the urinary system. The ureters carry the urine away from kidneys to the urinary bladder, which is a temporary reservoir for the urine. The urethra is a tubular structure that carries the urine from the urinary bladder to the outside. Kidneys The kidneys are the primary organs of the urinary system. The kidneys are the organs that filter the blood, remove the wastes, and excrete the wastes in the urine. They are the organs that perform the f unctions of the urinary system. The other components are accessory structures to eliminate the urine from the body. The paired kidneys are located between the twelfth thoracic and third lumbar vertebrae, one on each side of the vertebral column. The right kidney usually is slightly lower than the left because the liver displaces it downward. The kidneys protected by the lower ribs, lie in shallow depressions against the posterior abdominal wall and behind the parietal peritoneum. This means they are retroperitoneal. Each kidney is held in place by connective tissue, called renal fascia, and is surrounded by a thick layer of adipose tissue, called perirenal fat, which helps to protect it. A tough, fibrous, connective tissue renal capsule closely envelopes each kidney and provides support for the soft tissue that is inside. In the adult, each kidney is approximately 3 cm thick, 6 cm wide, and 12 cm long. It is roughly bean-shaped with an indentation, called the hilum, on the med ial side. The hilum leads to a large cavity, called the renal sinus, within the kidney. The ureter and renal vein leave the kidney, and the renal artery enters the kidney at the hilum. The outer, reddish region, next to the capsule, is the renal cortex. This surrounds a darker reddish-brown region called the renal medulla. The renal medulla consists of a series of renal pyramids, which appear striated because they contain straight tubular structures and blood vessels. The wide bases of the pyramids are adjacent to the cortex and the pointed ends, called renal papillae, are directed toward the center of the kidney. Portions of the renal cortex extend into the spaces between adjacent pyramids to form renal columns. The cortex and medulla make up the parenchyma, or functional tissue, of the kidney. The central region of the kidney contains the renal pelvis, which is located in the renal sinus and is continuous with the ureter. The renal pelvis is a large cavity that collects the urine as it is produced. The periphery of the renal pelvis is interrupted by cuplike projections called calyces. A minor calyx surrounds the renal papillae of each pyramid and collects urine from that pyramid. Several minor calyces converge to form a major calyx. From the major calyces the urine flows into the renal pelvis and from there into the ureter. Each kidney contains over a million functional units, called nephrons, in the parenchyma (cortex and medulla). A nephron has two parts: a renal corpuscle and a renal tubule. The renal corpuscle consists of a cluster of capillaries, called the glomerulus, surrounded by a double-layered epithelial cup, called the glomerular capsule. An afferent arteriole leads into the renal corpuscle and an efferent arteriole leaves the renal corpuscle. Urine passes from the nephrons into collecting ducts then into the minor calyces. The juxtaglomerular apparatus, which monitors blood pressure and secretes renin, is formed from modified cells in t he afferent arteriole and the ascending limb of the nephron loop. Ureter Each ureter is a small tube, about 25 cm long, that carries urine from the renal pelvis to the urinary bladder. It descends from the renal pelvis, along the posterior abdominal wall, behind the parietal peritoneum, and enters the urinary bladder on the posterior inferior surface. The wall of the ureter consists of three layers. The outer layer, the fibrous coat, is a supporting layer of fibrous connective tissue. The middle layer, the muscular coat, consists of inner circular and outer longitudinal smooth muscle. The main function of this layer is peristalsis to propel the urine. The inner layer, the mucosa, is transitional epithelium that is continuous with the lining of the renal pelvis and the urinary bladder. This layer secretes mucus which coats and protects the surface of the cells. Urinary Bladder The urinary bladder is a temporary storage reservoir for urine. It is located in the pelvic cavity, po sterior to the symphysis pubis, and below the parietal peritoneum. The size and shape of the urinary bladder varies with the amount of urine it contains and with pressure it receives from surrounding organs. The inner lining of the urinary bladder is a mucous membrane of transitional epithelium that is continuous with that in the ureters. When the bladder is empty, the mucosa has numerous folds called rugae. The rugae and transitional epithelium allow the bladder to expand as it fills. The second layer in the walls is the submucosa that supports the mucous membrane. It is composed of connective tissue with elastic fibers. The next layer is the muscularis, which is composed of smooth muscle. The smooth muscle fibers are interwoven in all directions and collectively these are called the detrusor muscle. Contraction of this muscle expels urine from the bladder. On the superior surface, the outer layer of the bladder wall is parietal peritoneum. In all other regions, the outer lay er is fibrous connective tissue. There is a triangular area, called the trigone, formed by three openings in the floor of the urinary bladder. Two of the openings are from the ureters and form the base of the trigone. Small flaps of mucosa cover these openings and act as valves that allow urine to enter the bladder but prevent it from backing up from the bladder into the ureters. The third opening, at the apex of the trigone, is the opening into the urethra. A band of the detrusor muscle encircles this opening to form the internal urethral sphincter. Urethra The final passageway for the flow of urine is the urethra, a thin-walled tube that conveys urine from the floor of the urinary bladder to the outside. The opening to the outside is the external urethral orifice. The mucosal lining of the urethra is transitional epithelium. The wall also contains smooth muscle fibers and is supported by connective tissue. The internal urethral sphincter surrounds the beginning of the urethr a, where it leaves the urinary bladder. This sphincter is smooth (involuntary) muscle. Another sphincter, the external urethral sphincter, is skeletal (voluntary) muscle and encircles the urethra where it goes through the pelvic floor. These two sphincters control the flow of urine through the urethra. In females, the urethra is short, only 3 to 4 cm (about 1. 5 inches) long. The external urethral orifice opens to the outside just anterior to the opening for the vagina. In males, the urethra is much longer, about 20 cm (7 to 8 inches) in length, and transports both urine and semen. The first part, next to the urinary bladder, passes through the prostate gland and is called the prostatic urethra. The second part, a short region that penetrates the pelvic floor and enters the penis, is called the membranous urethra. The third part, the spongy urethra, is the longest region. This portion of the urethra extends the entire length of the penis, and the external urethral orifice opens t o the outside at the tip of the penis.
