Question

Quizplus · Accepted Answer

The kidney releases the enzyme renin when blood pressure falls. Renin then converts angiotensinogen (a plasma protein) into angiotensin I, which is further converted by converting enzyme (ACE) in the lungs into angiotensin II, a potent vasoconstrictor that raises blood pressure. This autoregulatory mechanism helps maintain blood pressure within a normal range.
