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.
Alpha-2A adrenergic receptor activates Phospholipase C beta 3 or 2 (PLC-beta3 or PLC-beta2) when complex Guanine nucleotide binding protein (G protein) beta and gamma (G-protein beta/gamma) is released from the trimeric complex with G-protein alpha-i family (presumably by G-protein alpha-i2) [ 2 ], [ 3 ].n addition, Alpha-2A and Alpha-2C-1 adrenergic receptors, after activation of c-Src, can activate Shc / GRB2 / SOS without EGFR-transactivation [ 1 ]. Also, all three Alpha-2 adrenergic receptors stimulate v-akt murine thymoma viral oncogene homolog (AKT(PKB)) that is thought to activate ERK2 and ERK1.
