How does the renin-angiotensin-aldosterone system regulate mean arterial pressure?

Question

Quizplus · Accepted Answer

The renin-angiotensin-aldosterone system regulates mean arterial pressure by producing the hormone angiotensin II, which causes vasoconstriction and an increase in blood pressure. The system is activated when there is a decrease in blood pressure or blood volume, leading to the release of renin from the kidneys. Renin then converts angiotensinogen to angiotensin I, which is converted to angiotensin II by the enzyme ACE (angiotensin converting enzyme). Angiotensin II stimulates the release of aldosterone, which promotes sodium and water reabsorption in the kidneys, leading to an increase in blood volume and blood pressure.
