SlideVilla’s PPT for Urinary System (Water control and nitrogen disposal) templates with slides.
- The urinary system maintains homeostasis in several ways:
- Removal of urea (nitrogenous waste) from the bloodstream.
- Control of water and salt balance in the bloodstream.
- Involved in blood pressure regulation.
The kidneys produce two important hormones. What do they control?
1.Blood pressure and volume
- Renin is an enzyme released by the kidneys in response to a drop in blood pressure.
- Renin catalyzes the production of angiotensin, a hormone that causes arterioles to constrict, raising blood pressure. This also causes water retention. How does this maintain homeostasis of blood pressure?
- A second response to low blood pressure is the release of erythropoietin, another hormone.
- Erythropoietin travels to the bone marrow and stimulates the production of new blood cells. How does this maintain homeostasis?
Ammonia and Urea
- Ammonia is toxic and highly water soluble.
- The liver turns ammonia into urea, which is less toxic and less soluble.
- Besides toxicity, why is it advantageous for land animals to convert highly water-soluble ammonia into less-soluble urea?
- What could be a health risk of going on an extremely high protein diet?
Anatomy of the Kidney
- Main structures of the mammalian kidney:
- renal cortex
- renal medula
- renal pelvis
- This is the only place in the system where the blood is actually “filtered.”
- Blood pressure is used to push plasma through capillary walls and into the Bowman’s capsule
