What are the main functions of the kidney?

To eliminate waste products
The types of waste products that the kidneys primarily have to eliminate are called “urea” and “creatinine”.

To control the amount of fluid
Healthy kidneys control the amount of fluid in the body and help to eliminate excess fluid from the blood.

To control blood pressure
Blood pressure needs to be maintained at the proper level so that you have enough blood in all parts of your body. Maintaining blood pressure at its normal level reduces the risk of having heart problems. If blood pressure is very high, the heart has to work harder to pump blood through the blood vessels.

To facilitate the production of red blood cells
The kidneys produce a hormone called erythropoietin, which helps the body produce red blood cells.

To maintain healthy bones
The kidneys regulate the amount of phosphorus and calcium in the blood. Phosphorus and calcium balance is important in promoting healthy bones.
