You have two kidneys. They are shaped like beans with concave and convex sides and are about the size of a fist. They are located at the bottom of the rib cage, one to the left and one to the right of your spine.
Functions of kidneys
Your kidneys are multi-functional. But their main job is to get rid of waste. They remove the waste products that arises when you digest food and drink, as well as excess organic molecules (such as glucose).
