DEFINITION:
- angiotensin II
-
An octapeptide hormone formed by the action of angiotensin-converting enzyme (peptidyl-dipeptidase A) on angiotensin I, chiefly in the lungs but also at other sites, including the blood vessel walls, uterus, and brain. It is a powerful vasopressor and stimulator of aldosterone secretion by the adrenal cortex, and it also functions as a neurotransmitter. Its vasopressor action raises blood pressure and diminishes fluid loss in the kidney by restricting blood flow.
