4. angiotensin
   A peptide hormone. Angiotensinogen (renin substrate) is a 60 kD polypeptide released from the liver and cleaved in the circulation by renin to form the biologically inactive decapeptide angiotensin I. This is in turn cleaved to form active angiotensin II by Angiotensin Converting Enzyme (ACE). Angiotensin II causes contraction of vascular smooth muscle, and thus raises blood pressure, and stimulates aldosterone release from the adrenal glands. An …

7. angiotensin
   (ACE) (an″je-o-ten´sin) a vasoconstrictive substance formed in the blood when renin is released from the juxtaglomerular apparatus in the kidney. The enzymatic action of renin acts on angiotensinogen to form the decapeptide angiotensin I, which is relatively inactive. It in turn is acted upon by p...

11. Angiotensin
    `Angiotensin`, a peptide hormone, causes blood vessels to constrict, and drives blood pressure up. It is part of the renin-angiotensin system, which is a major target for drugs that lower blood pressure. Angiotensin also stimulates the release of aldosterone, another hormone, from the adrenal cortex...
