Meaning and Definition
A peptide hormone in the blood that constricts blood vessels and raises blood pressure.
A component of the renin-angiotensin system (RAS), a hormone system that regulates blood pressure and fluid balance. It exists in several forms (e.g., angiotensin I, II) and is a key target for cardiovascular medications.
Dialectal Variation

FAQ
Frequently Asked Questions
It is essential for regulating blood pressure and fluid balance. However, excessive or inappropriate activity of the angiotensin system is a major contributor to hypertension and heart failure.
Angiotensin I is an inactive precursor. Angiotensin-converting enzyme (ACE) removes two amino acids, converting it into angiotensin II, which is the potent, active form that affects blood vessels.
Because the renin-angiotensin system is a central pathway for blood pressure control. Blocking it with ACE inhibitors or angiotensin receptor blockers (ARBs) is a highly effective way to treat hypertension, heart failure, and kidney disease.
It is extremely unlikely. You might see it in simplified health articles or in television advertisements for prescription blood pressure medications aimed at the general public.

Mnemonic
Think: 'ANGIO' (relating to blood vessels, as in angiography) + 'TENSIN' (like tension/pressure). Angiotensin creates tension in your blood vessels.
