Definition & Meaning of "angiotensin"

What is "angiotensin"?

Angiotensin is a hormone involved in the regulation of blood pressure and fluid balance. It is produced in response to low blood pressure or decreased blood flow in the kidneys. Angiotensin acts on blood vessels, causing them to constrict and increase blood pressure. It also stimulates the release of aldosterone from the adrenal glands, which promotes the reabsorption of sodium and water in the kidneys, further regulating fluid balance. Overall, angiotensin plays a crucial role in maintaining proper blood pressure and fluid levels in the body.
