Angiotensin II increases blood pressure by
A) vasoconstriction of systemic arteries and stimulation of aldosterone
B) vasodilation of systemic arteries and stimulation of aldosterone
C) vasoconstriction of systemic arteries and stimulation of antidiuretic hormone
D) vasodilation of systemic arteries and stimulation of antidiuretic hormone

Question

Quizplus · Accepted Answer

Angiotensin II causes vasoconstriction of systemic arteries, which raises blood pressure, and also stimulates the release of aldosterone, which promotes sodium and water retention, further increasing blood volume and pressure. Vasodilation and the stimulation of antidiuretic hormone would have the opposite effect, lowering blood pressure.
