| renin-angiotensin-aldosterone system | The hormones, renin, angiotensin, and aldosterone work together to regulate blood pressure. A sustained fall in blood pressure causes the kidney to release renin. This is converted to angiotensin in the circulation. Angiotensin then raises blood pressure directly by arteriolar constriction and stimulates adrenal gland to produce aldosterone which promotes sodium and water retention by kidney, such that blood volume and blood pressure increase.

| renin-angiotensin system | <physiology> A system consisting of renin, angiotensin-converting enzyme, and angiotensin II. Renin, an enzyme produced in the kidney, acts on angiotensinogen, an alpha-2 globulin produced by the liver, forming angiotensin I. The converting enzyme contained in the lung acts on angiotensin I in the plasma converting it to angiotensin II, the most powerful directly pressor substance known. It causes contraction of the arteriolar smooth muscle and has other indirect actions mediated through the adrenal cortex. (25 Jun 1999) |
| 1-sarcosine-8-isoleucine angiotensin II | <chemical> An angiotensin II analog which acts as a highly specific inhibitor of angiotensin II. Pharmacological action: angiotensin-converting enzyme inhibitors, antihypertensive agents. Chemical name: Angiotensin II, 1-(N-methylglycine)-8-L-isoleucine- (12 Dec 1998) |
