Question

Quizplus · Accepted Answer

Vasopressin, also known as antidiuretic hormone (ADH), is the hormone that directly controls water reabsorption by the kidneys. It is produced in the hypothalamus and released by the pituitary gland in response to changes in blood osmolality (concentration of solutes in the blood) or blood volume. Vasopressin acts on the cells of the collecting ducts in the kidneys to increase water reabsorption, which helps to conserve and maintain the body's fluid balance.
