For Patients & Families: About Your Kidneys

about your kidneys

know your kidneys

overview and introduction

 

The kidneys are a pair of bean shaped organs whose job it is to filter your blood. Each kidney is about the size of an adult fist, and they are located on either side of the spine, just below the rib cage. Although they are small, your kidneys perform many complex and vital functions that keep the rest of the body in balance. For example, kidneys:

 

  • Help remove waste and excess fluid

  • Filter the blood, keeping some compounds while removing others

  • Control the production of red blood cells

  • Make vitamins that control growth

  • Release hormones that help regulate blood pressure

  • Help regulate blood pressure, red blood cells, and the amount of certain nutrients in the body, such as calcium and potassium.

Amazingly, all of the blood in your body passes through your kidneys several times a day.
