Antidiuretic hormone
Antidiuretic hormone (ADH), or
arginine vasopressin (AVP), is a
peptide hormone produced by the
hypothalamus, and stored in the posterior
pituitary gland until the hypothalamus signals its release in response to a change in serum osmolarity or blood volume. ADH acts on the
kidneys at the renal collecting duct, concentrating the urine by promoting the reabsorption of
water and
salt.\n
