Question

Quizplus · Accepted Answer

ADH (antidiuretic hormone) has the greatest effect on the reabsorption of water in the distal tubule and collecting duct of the nephron. In response to ADH, the walls of the distal tubule and collecting duct become more permeable to water, allowing more water to be absorbed back into the bloodstream. This helps to regulate water balance in the body and prevent dehydration. ADH has little to no effect on the proximal tubule or the ascending and descending loops of Henle.
