MEDICAL PHYSIOLOGY

Detailed explanation-1: -Angiotensin-converting enzyme (ACE) plays a central role in generating angiotensin I I from angiotensin I, and capillary blood vessels in the lung are one of the major sites of ACE expression and angiotensin II production in the human body.

Detailed explanation-2: -Angiotensin I is produced by the action of renin on a protein called angiotensinogen, which is formed by the liver. Angiotensin enzymes are secreted by the kidneys. Angiotensin I is transformed into angiotensin IIby the action of the enzyme called angiotensin-converting enzyme (ACE).
