Renal Assignment Bhajan Singh Bains S2620456 Laboratory: Thursday 1 pm to 4 pm Group 6 Tutor: Mr. bear Course convener: Dr Suzie Owens Introduction The purpose of this lab appellative is to culture the effects of exercise, caffeine and salt (sodium chloride) on the kidneys. The criterion of addle produced is measured e very twenty proceedings to take over whether the salt, caffeine and exercise developments or precipitates peeing take. The mechanism of inhabit up to involved in the maintenance of homeostasis by the kidneys and the results obtained in the laboratory experiment would be discussed in detail plot of land answering the ten questions. The nephritic excretion systems of angiotensin, ADH and aldosterone are very crucial in maintaining blood pressure. Vascular tidy sum is keep by piss excretion or water system reabsorption by the kidneys. Renin is an enzyme inflammationd from renal arterioles wh en BP drops. Renin converts angiotensinogen into angiotensin I. angiotensin I is wherefore converted to angiotensin II by adept (angiotensin converting enzyme). ACE is present in the endothelium of heart, brain, skeletal muscles, kidneys and pulmonary vessels. Angiotensin II is a very powerful vasoconstrictor and because has a great effect on renal BP by enhancing renal flow and urine production.
Angiotensin II as well triggers the release of aldosterone which acts on renal tubules to enlarge reabsorption of water and sodium via the sodium potassium pump. 1. Effects of exercise on urine production. The r esults obtained from this experiment indicat! e that there is minimal increase in urine production for the first forty minutes. The urine production after sixty minutes showed a striking increase (approximately 10 mls/minute). There is a slight decrease in urine production after 80 minutes (7 ml/min) and after 100 minutes (7.5 ml/min) weewee output (Mls/min) metre (mins) The mechanism of...If you want to get a full essay, set it on our website:
