Water will move by osmosis only in the presence of ADH in the:
A) distal tubule.
B) collecting duct.
C) ascending limb of Henle.
D) Both A and B are correct.

Question

Quizplus · Accepted Answer

Water reabsorption in the distal tubule and collecting duct is regulated by the antidiuretic hormone (ADH). ADH increases the permeability of the distal tubule and collecting duct to water, facilitating water reabsorption and concentrating the urine. The ascending limb of Henle is impermeable to water and does not require ADH for water movement.
