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.

- Nephron Structure and Circulation Fill in the blanks to complete some thoughts on how the nephron works. The blood first enters the (21), which filters small molecules out of the afferent arteriole. Larger molecules such as (22) do not enter the nephron. Proteins (Can or Can not?, 23) enter the nephron. Amino acids and glucose are placed back into the blood stream by the cells of the (24). As the material that becomes urine travels down the descending limb of the loop, a good amount of (25) is removed. The ascending limb is responsible for removing (26). through the process of active transport. Urine is further concentrated by removal of some water in the collecting duct.arrow_forwardThe desert kangaroo rat does not produce dilute, liquid urine, but instead produces thick, highlyconcentrated urine.
