How do my kidneys work

Size and location in the body

The kidneys are bean-shaped and the size of your fist. They lie in the middle of the back, on each side of the spine.

Normally, there are two kidneys in our bodies. Among other things, they are responsible for the water balance and the filtering of toxins.

Function of the kidneys

Your kidneys work 24 hours per day

All of the blood is filtered about 300 times throughout the day if the kidneys are healthy

On average, around 1,500 liters of blood flow through the kidneys a day
