WebVasopressin (arginine vasopressin, AVP; antidiuretic hormone, ADH) is a peptide hormone formed in the hypothalamus, then transported via axons to the posterior pituitary, which releases it into the blood. This increases blood volume, cardiac output and arterial pressure. A secondary function of AVP is vasoconstriction.

WebWhat does ADH stimulate? Antidiuretic hormone stimulates water reabsorbtion by stimulating insertion of "water channels" or aquaporins into the membranes of kidney tubules. These channels transport solute-free water through tubular cells and back into blood, leading to a decrease in plasma osmolarity and an increase osmolarity of urine. WebADH signals its target cells in the kidneys to reabsorb more water, thus preventing the loss of additional fluid in the urine.
