Angiotensin II causes all except
Ans. (C) Vasodilation(Ref: Ganong Review of Medical Physiology 22nd; KDT 8th/e p525)*Angiotensin II binds to AT1 receptors and causes vasoconstriction and release of aldosterone.*Angiotensin II is one of the most potent vasoconstrictors in body.*Angiotensin II increases thirst sensation through the subfornical organ (SFO) of the brain.*It increases secretion of ATCH in the anterior pituitary.*It also potentiates the release of norepinephrine by direct action on postganglionic sympathetic fibers.
Stimulates release of ADH
Increases thirst
Vasodilation
Stimulates aldosterone release
