Angiotensin is a hormone that stimulates vasoconstriction and increases blood pressure. Which effect would also be expected from angiotensin function?
A.
increased secretion of sodium in the kidney
B.
decreased secretion of sodium in the kidneys
C.
increased reabsorption of sodium in the kidneys
D.
decreased reabsorption of sodium in the kidneys
Suppose the kidneys of a person are damaged, can you predict what is going to happen to him?
Part A
Why is control over blood [Ca2+] and [Red Blood Cell] crucial? Choose one hormone involved in either of these homeostatic systems that regulate the concentration of these ions/cells and describe how it functions in homeostasis. Remember to include the name of the gland that secretes it.
Part B
Choose one molecule that is reabsorbed by the nephron and describe the process by which it is reabsorbed.
