Question

the hormone adh promotes water reabsorption through the wall(s) of the

multiple choice
distal tubule and collecting duct
descending limb of the nephron loop
proximal tubule and collecting duct
ascending limb of the nephron loop

Explanation:

ADH (antidiuretic hormone) acts on the distal tubule and collecting duct. It increases the permeability of these segments to water, allowing more water to be reabsorbed back into the bloodstream. The descending limb of the nephron loop is permeable to water without the influence of ADH. The proximal tubule reabsorbs a large amount of water but its reabsorption is not regulated by ADH. The ascending limb of the nephron loop is impermeable to water.

Answer:

distal tubule and collecting duct
