Question

Quizplus · Accepted Answer

When antidiuretic hormone is present, it causes water reabsorption in the kidney, which leads to a reduction in urine volume. This occurs because the hormone causes the walls of the collecting duct to become permeable to water and inserts aquaporins in the membrane of the collecting duct cells, which allows water to move from the urine in the collecting duct into the interstitial fluid surrounding the duct. As a result, urine becomes more concentrated. Therefore, all the events listed in options B, C, and D occur when antidiuretic hormone is present. Option A, however, is incorrect, as water does not diffuse into the collecting duct from the interstitial fluid when antidiuretic hormone is present, but rather, the opposite occurs.
