Your heart is a machine, the most important organ in your body. Who would think that something about the size of your fist would be so vital. How much do you know about your heart and how it works?

The main job of the heart is to pump blood to every part of the body. The walls of the heart are made of really strong muscles that squeeze and relax to do this job.
