Renin

Renin is a hormone produced by the kidneys that helps control blood pressure. Renin works with other chemicals to narrow (constrict) blood vessels, which increases blood pressure; a decrease in renin levels helps lower blood pressure.

Normally, this mechanism keeps blood pressure within a healthy range. However, some people develop chronic high blood pressure (hypertension). When this occurs, medications may be used that block the action of renin on blood vessels.
