Vasopressin, also known as antidiuretic hormone (ADH), is produced in the hypothalamus and secreted by the posterior pituitary gland. It increases the permeability of the distal and collecting tubules to water, promoting water reabsorption. Its secretion is stimulated by a water deficit in the body, such as dehydration, and it helps to conserve water and maintain water balance. Therefore, all of the above characteristics are true for vasopressin.
