Why must you have a heart?

The heart pumps blood around your body. Without blood, your body parts cannot get the fuel they need - oxygen and food. The heart has to keep pumping so that all of your body is supplied with fuel. If your heart stops pumping, your blood stops flowing and you will die as your body parts run out of nutrients and oxygen.
