Question

Quizplus · Accepted Answer

Decreased blood flow to the kidneys stimulates the release of the enzyme renin from specialized cells in the kidneys, known as juxtaglomerular cells. Renin acts on angiotensinogen, a protein in the blood, to convert it to angiotensin I. Angiotensin I is then converted to angiotensin II by an enzyme called angiotensin-converting enzyme (ACE). Angiotensin II is a potent vasoconstrictor and stimulates the release of aldosterone, promoting sodium and water retention to increase blood volume and restore blood pressure.
