kidneys are fist-sized organs located at the bottom of your rib cage, on both sides of your spine. They perform several functions.

Most importantly, they filter waste products, excess water, and other impurities from your blood. These waste products are stored in your bladder and later expelled through urine.

In addition, your kidneys regulate pH, salt, and potassium levels in your body. They also produce hormones that regulate blood pressure and control the production of red blood cells.

Your kidneys are also responsible for activating a form of vitamin D that helps your body absorb calcium for building bones and regulating muscle function.

Maintaining kidney health is important to your overall health and general well-being. By keeping your kidneys healthy, your body will filter and expel waste properly and produce hormones to help your body function properly.
