_____________ directly increases vasoconstriction.

Question

Quizplus · Accepted Answer

Angiotensin II is known as a potent vasoconstrictor, causing constriction of both arterioles and veins. It is produced by the renin-angiotensin-aldosterone system in response to decreased blood pressure or blood volume, and also stimulates the release of aldosterone to increase blood volume through sodium and water retention. ADH works to increase water reabsorption in the kidneys to maintain blood volume but does not have a direct effect on vasoconstriction. Atrial natriuretic hormone, on the other hand, opposes the actions of aldosterone and promotes vasodilation.
