Angiotensin ii



any of three oligopeptides occurring in plasma, an inactive form (angiotensin I) and two varieties (angiotensin II and angiotensin III) that elevate blood pressure and stimulate the adrenal cortex to secrete aldosterone.
noun
a peptide of physiological importance that is capable of causing constriction of blood vessels, which raises blood pressure

angiotensin II n.
An octapeptide that is a potent vasopressor and a powerful stimulus for production and release of aldosterone from the adrenal cortex.

angiotensin an·gi·o·ten·sin (ān’jē-ō-těn’sĭn)
n.
Any of a group of peptides with vasoconstrictive activity that function physiologically in controlling arterial pressure.
angiotensin
(ān’jē-ō-těn’sĭn)
Any of three polypeptide hormones that function in the body in controlling arterial pressure. The most important is known as angiotensin II, a powerful vasoconstrictor that stimulates steroid production by the adrenal glands, reduces fluid loss from the kidneys, and also functions as a neurotransmitter. Angiotensin II is formed from inactive angiotensin I by the action of angiotensin-converting enzyme (or ACE). See also ACE inhibitor, renin.
