Question

Why are the loop of Henle and vasa recta important for the formation of concentrated urine?

a) They reabsorb water from filtrate
b) They regulate electrolyte balance
c) They concentrate solutes in the medulla
d) All of the above

Answer 1

The loop of Henle and vasa recta are important for the formation of concentrated urine as they reabsorb water, regulate electrolyte balance, and concentrate solutes in the medulla.

Step-by-step explanation:

The loop of Henle and vasa recta are important for the formation of concentrated urine because they perform several functions. The loop of Henle reabsorbs water from the filtrate in the descending limb and regulates electrolyte balance in the ascending limb. Additionally, the loop of Henle concentrates solutes in the medulla, creating an osmotic gradient that allows for the reabsorption of more water.
