Question

Quizplus · Accepted Answer

Antidiuretic hormone (ADH) stimulates the kidneys to conserve water. This is done by increasing the reabsorption of water in the collecting ducts of the nephron, leading to increased water retention and decreased urine volume. ADH is secreted by the hypothalamus and released by the posterior pituitary gland in response to factors such as high blood osmolality, low blood pressure, and stress.
