What Do Kidneys Do?

7. Production of Renin
Renin is an important enzyme produced by the kidneys. The enzyme can also be considered a hormone since it contains a receptor. It is an important component of the renin-angiotensin-aldosterone hormonal system. In this system, the hormones work together to maintain the body’s long-term blood pressure.
Production of renin is triggered by the sympathetic nervous system, a drop in arterial blood pressure, or decreased sodium chloride levels within the kidneys.
