Which of the following correctly describes water movement across the epithelial cells lining the collecting duct?

Question

Quizplus · Accepted Answer

Water movement across the epithelial cells of the collecting duct is facilitated by aquaporins. Aquaporin-2 channels are inserted into the apical membrane in response to ADH (antidiuretic hormone), allowing water to move from the tubular lumen into the cell. Aquaporin-3 channels are present in the basolateral membrane, allowing water to exit the cell into the bloodstream.
