ADH has the greatest effect on the reabsorption of water in the:
A)proximal tubule.
B)ascending nephron loop.

D)distal tubule.

Question

Quizplus · Accepted Answer

ADH acts primarily on the distal tubule and collecting ducts of the nephrons to increase water reabsorption. In these regions, ADH stimulates the insertion of aquaporin-2 channels into the luminal membrane of the tubular cells, which allows water to passively flow out of the tubules and into the interstitium, where it can be reabsorbed into the bloodstream.
