Question

Quizplus · Accepted Answer

Angiotensin II increases Na⁺ reabsorption by stimulating aldosterone secretion, which helps to retain sodium and water in the body, leading to an increase in blood volume and blood pressure. It is activated when ECF volume and arterial blood pressure are decreased, and plays a major role in the renin-angiotensin-aldosterone system (RAAS) that regulates blood pressure and fluid balance in the body.
