The kidneys produce a special enzyme (enzyme) renin, which converts into active forms of angiotensins involved in regulating blood pressure. Determining renin activity in the blood is used to diagnose arterial hypertension. Renin is a peptidase enzyme secreted by the kidneys into the bloodstream in response to a stressful situation. Excessive renin production can lead to the development of renal hypertension syndrome.
