Function of vasopressin
assistant
The correct answer is  Vasopressin- a hormone secreted by cells of the hypothalamic nuclei and stored in the posterior pituitary for release as necessary; it stimulates contraction of the muscular tissues of the capillaries and aerioles, raising the blood pressure, and increases peristalsis, exes some influence on the uterus, and influences resorption of water by the kidney tubules, resulting in concentration of urine.Ref: Ganong&;s review of medical physiology; 24th edition; page no:-303
