ADH is formed in the [[Hypothalamus/en|hypothalamus]], transported into the posterior pituitary gland and released into the bloodstream through various regulatory mechanisms. ADH has an antidiuretic effect by promoting water reabsorption in the distal tubules as well as in the collection tubes of the kidney. This means that as little water as possible is lost to the body. The vasopressor effect of ADH leads to arterial vasoconstriction and thus to an increase in blood pressure. ADH distribution is controlled by the osmoregulatory system.
