a thick, brown-green fluid secreted by the liver which is alkaline in its reactions, containing bile salts, bile pigments, CHOLESTEROL and inorganic salts. Bile is transferred from the liver to the DUODENUM via the bile duct which in many mammals contains a reservoir called the gall bladder.
Vasopressin, also known as arginine vasopressin (AVP), antidiuretic hormone (ADH), or argipressin, is a neurohypophysial hormone found in most mammals.Its two primary functions are to retain water in the body and to constrict blood vessels.asopressin regulates the body's retention of water by acting to increase water reabsorption in the kidney's collecting ducts, the tubules which receive the very dilute urine produced by the functional unit of the kidney, the nephrons.
