Question

Which of the following contributes to the formation of a hyperosmotic
environment in the medulla of the kidney?
a. the effects of ADH on water permeability of the ascending limb
of the loop of Henle
b. the impermeability of the ascending limb of the loop of Henle
to water
c. the symport of Na+, K+, and Cl− out of the ascending limb of the
loop of Henle
d. Both a and c are correct.
e. Both b and c are correct.

Expert Solution
Step 1

Osmoregulation is the third of three systems that filter blood and produce urine. Controlling the water content of a living organism's blood, bone, or cytoplasm is known as osmoregulation.

Step 2

The hyperosmotic environment in the renal medulla appears to be essential for bacterial pyelonephritis. Since it inhibits the activity of polymorphonuclear leukocytes. The ascending limb of the Henle loop's impermeability to water and the cotransport of Na+, K+, and Cl- out of the ascending limb of the Henle loop's ascending limb.

Hence, the correct option is e.
