Question

Quizplus · Accepted Answer

Antidiuretic hormone (ADH), also known as vasopressin, directly controls the reabsorption of water from the collecting ducts. ADH is produced in the hypothalamus and released from the posterior pituitary gland in response to changes in blood osmolality (concentration). It causes the insertion of aquaporin channels in the cell membranes of the collecting ducts, allowing water to move back into the bloodstream and thereby increasing water reabsorption.
