Question

Quizplus · Accepted Answer

ADH increases the permeability of the late distal tubule and cortical collecting ducts to water, allowing for reabsorption of water back into the bloodstream and ultimately resulting in a decrease in urine output. Option A is incorrect as ADH promotes water reabsorption and decreases urine output. Option C is incorrect as ADH causes the kidneys to produce concentrated urine by increasing the reabsorption of water. Option D is incorrect as ADH secretion is primarily regulated by the osmolality of the blood and volume status, not potassium levels.
