WE have two kidneys that are located at the back of our abdomens.

These organs control the amount of fluid in our bodies and filter liquid waste from our blood to keep it pure.

This filtered waste is then sent to our bladders, from which it is expelled from time to time as urine. - The New Children's Encyclopedia, Dorling Kindersley
