Question

Quizplus · Accepted Answer

With age, the sensitivity to ADH decreases, which can lead to decreased water reabsorption and increased urine output.

Answer: D
 With age, there is a decrease in the number and function of nephrons in the kidney, leading to a reduced ability to concentrate urine. This results in a greater need for reabsorption of water by the remaining nephrons to maintain fluid balance.
