Arginine vasopressin (AVP), also known as vasopressin, argipressin or antidiuretic hormone (ADH), is a neurohypophysial hormone found in most mammals. Its two primary functions are to retain water in the body and to constrict blood vessels. Vasopressin regulates the body's retention of water by acting to increase water absorption in the collecting ducts of the kidney nephron. Vasopressin increases water permeability of the kidney's collecting duct and distal convoluted tubule by inducing translocation of aquaporin-CD water channels in the kidney nephron collecting duct plasma membrane. Vasopressin is a peptide hormone that controls the reabsorption of molecules in the tubules of the kidneys by affecting the tissue's permeability. It also increases peripheral vascular resistance, which in turn increases arterial blood pressure. It plays a key role in homeostasis, by the regulation of water, glucose, and salts in the blood. It is derived from a preprohormone precursor that is synthesized in the hypothalamus and stored in vesicles at the posterior pituitary. Most of it is stored in the posterior pituitary to be released into the bloodstream. However, some AVP may also be released directly into the brain, and accumulating evidence suggests it plays an important role in social behavior, bonding, and maternal responses to stress.
Arginine Vasopressin AKA antidiuretic hormone (ADH) is a hormone released from the posterior pituitary gland and it helps in water retention in the kidneys and prevents water loss.

There are actually a few other names for vasopressin. Some of these names include arginine vasopressin, antidiuretic hormone, and argipressin.
Vasopressin( Anti-diuretic hormone) is a naturally occurring hormone in the body that is secreted by the posterior lobe of the pituitary gland. It constricts blood vessels, raises blood pressure, stimulates water reabsorption, and reduces excretion of urine.
POSTERIOR PITUTARY GLAND produce vasopressin or anti-diuretic hormone.

vasopressin is an antidiuretic hormone responsible for increased permeability of the distal tubules of the kidney, increasing water reabsorption and reducing urine volume.
Vasopressin is produced in the postieror pituitary gland. This glad also produces oxytocin.
Too little vasopressin (or antidiuretic hormone) will lead to a condition called diabetes insipidus. This will mean that a person will be thirsty, and will urinate dilute urine (some times 3 to 4 liters per day). Vasopressin is the hormone that causes water to be reabsorbed in the kidneys. If you don't have enough vasopressin, then the kidneys will not reabsorb enough water, and excessive water will be excreted in the urine. This will cause dehydration and electrolyte imbalance in the body. Synthetic antidiuretic hormone is available (vasopressin and DDAVP).
As ADH (which is also known as vasopressin) causes direct water reabsorption from the kidney tubules, salts and wastes are concentrated in what will eventually be excreted as urine. The hypothalamus controls the mechanisms of ADH secretion, either by regulating blood volume or the concentration of water in the blood.
