When renin is released from the kidney, it triggers the formation of angiotensin I from angiotensinogen, a plasma protein. Renin cleaves angiotensinogen to produce angiotensin I, which is then converted to angiotensin II by the action of angiotensin-converting enzyme (ACE) in the lungs. Angiotensin II is a potent vasoconstrictor and increases blood pressure.
