- Angiotensin II
- Produced from upstream action of renin
- Renin cleaves the precursor angiotensinogen (made in liver) to form angiotensin I
- Angiotensin-converting enzyme (ACE) from endothelial cells then cleaves angiotensin I to form angiotensin II in the lungs
- Produced from upstream action of renin
- Angiotensin II raises BP by:
- Inducing release of aldosterone and ADH
- Increases BP by increasing blood volume through water retention
- Inducing constriction of arterioles
- Inducing release of aldosterone and ADH
- Increases BP without changing blood volume
- Increases BP without changing blood volume
- Increases arterial pressure in kidneys
