Vasoconstriction and secretion of aldosterone are brought about by:
A)angiotensin II, to raise blood pressure
B)angiotensin I, to lower blood pressure
C)angiotensinogen, to lower blood pressure
D)renin, to raise blood pressure

Question

Quizplus · Accepted Answer

Vasoconstriction and secretion of aldosterone are both stimulated by angiotensin II, which is a hormone released in response to low blood pressure. This helps to increase blood pressure by constricting blood vessels and retaining salt and water in the body. Options B, C, and D are incorrect as they do not accurately describe the role of these hormones in regulating blood pressure.
