Definitions

A peptide hormone that causes blood vessels to constrict, and drives blood pressure up. It is part of the renin-angiotensin system.
Angiotensin, a quiet storm within, tightens the riverways of life, urging the heart's pulse to dance with fierce intent.

Example: Angiotensin II increases blood pressure by constricting the blood vessels.

1940s: from angio- 'blood vessel' + tensive, suggested by hypertension.
