Angiotensin-converting enzyme. Angiotensin-converting enzyme (EC 3.4.15.1), or ACE, is a central component of the renin-angiotensin system (RAS), which controls blood pressure by regulating the volume of fluids in the body. It converts the hormone angiotensin I to the active vasoconstrictor angiotensin II.
Renal Artery Stenosis. Renal artery stenosis (RAS) is the narrowing of one or both arteries that carry blood to the two kidneys. âRenalâ means âkidneyâ and âstenosisâ means ânarrowing.â RAS can cause high blood pressure and reduce kidney function.RAS is often overlooked as a cause of high blood pressure.he arteries that carry blood to the kidneysâcalled the renal arteriesâbranch off directly from the abdominal aorta, the main vessel from the heart that supplies blood to most of the bodyâs organs. Healthy kidneys filter out wastes and extra fluid from the blood that passes through them.
