angiotensin

Angiotensin is a hormone involved in regulating blood pressure and fluid balance. When blood pressure drops or sodium levels are low, the body releases enzymes that produce angiotensin. This hormone causes blood vessels to constrict, which increases blood pressure. It also signals the release of another hormone called aldosterone, prompting the kidneys to retain sodium and water, further raising blood volume and pressure. Overall, angiotensin plays a key role in maintaining steady blood pressure and ensuring organs receive enough blood to function properly.
