Renal Assignment Bhajan Singh Bains S2620456 Laboratory: Thursday 1 pm to 4 pm Group 6 Tutor: Mr. founder Course convener: Dr Suzie Owens Introduction The purpose of this lab appellative is to conduct the effects of exercise, caffeine and salt (sodium chloride) on the kidneys. The criterion of arrive at produced is measured e very twenty minutes to offer whether the salt, caffeine and exercise developments or reductions piddle take. The mechanism of bonk up to involved in the maintenance of homeostasis by the kidneys and the results obtained in the laboratory experiment would be discussed in detail turn answering the ten questions. The nephritic excretion systems of angiotensin, ADH and aldosterone are very crucial in maintaining blood pressure. Vascular heap is keep by pee excretion or irrigate reabsorption by the kidneys. Renin is an enzyme inflammationd from renal arterioles when BP drops. Renin con verts angiotensinogen into angiotensin I. angiotonin I is wherefore converted to angiotensin II by straits (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 then has a great effect on renal BP by enhancing renal flow and urine production. Angiotensin II also triggers the release of aldosterone which acts on renal tubules to join on reabsorption of water and sodium via the sodium potassium pump. 1. Effects of exercise on urine production. The results obtained from this experiment indicate that there is minimal increase in urine production for the first forty minutes. The urine production after sixty minutes showed a outstanding 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) body of water output (Mls/min) ! metre (mins) The mechanism of...If you want to get a full essay, set it on our website:
