Antidiuretic hormone (vasopressin) works at the level of the collecting duct to either increase absorption of water in order to maintain plasma volume and thus blood pressure. <span>This hormone is synthesized by special nerve cells of the hypothalamus and then transported to the pituitary gland where the hormone is released from vesicles into the bloodstream.
