The heart is arguably the most important organ. Although only the size of a fist, it is held responsible for pumping blood through our entire body.

Given the heart’s arduous task of supplying the body with blood every day, it must be well taken care of. A heart that is improperly cared for may develop heart disease, the leading cause of death among Americans.

Let’s take a closer look at the workings of this fascinating organ through the illustrations and animations created by the Medical Illustration Sourcebook Artists:
