Definition


Vasopressin, also known as arginine vasopressin (AVP) or antidiuretic hormone (ADH), is a protein secreted by the hypothalamus gland then released by the pituitary gland. This hormone is involved in regulating blood volume circulating in the body and water retention. It primarily impacts on the arteries by making them contract, thus causing blood pressure to increase, as well as impacting the kidneys making them retain more water by boosting their reabsorption activity. When the body is dehydrated, more vasopressin is secreted, while secretion is stopped when hydration levels increase.
