ANGIOTENSIN

Written by

Angiotensin is a peptide that occurs in two forms: I and II. The former results from the action of the ENZYME, RENIN on alpha globulin (a protein) produced by the liver and passed into the blood. During passage of the blood through the lungs, angiotensin I is converted into an active form, angiotensin II, by an enzyme. This active form constricts the blood vessels and stimulates the release of two hormones – VASOPRESSIN and ALDOSTERONE – which raise the blood pressure. (See also
