If you are thinking of the organ, the heart, its main function is to pump blood throughout the body. Blood circulation is vital because this is how most of the organs of your body are able to get nutrients and oxygen as well as get rid of waste products.
If there was no heart, the blood in your body would settle down in the lower parts because there would be nothing to work against gravity.
So the heart is the pump for the blood. It pushes the blood to, and through the lungs so that new oxygen can enter the bloodstream and carbon dioxide (and other gases) can leave the blood. The heart also pumps the blood through the various organs that perform specialized functions, such as the liver and kidneys, which work to remove waste products from the blood. The heart also pushes the blood around your whole body, even forcing the blood into the capillaries that surround most living tissue in your body.
This is why people with heart problems often have swelling in their hands and especially their feet. It takes a lot of force to move the blood throughout the vessels in your toes. When you heart isn't working with enough force blood can pool, or gather in the tissues that are the farthest from the heart.
People have four chambers in their heart, and each pumps blood at a different stage. This is why it is so dangerous when the heart's rhythm is interrupted. It's as if there were four pumps working together when one starts pumping at a different rate or at a different force than the other pumps.
Your heart doesn't have its own "brain" to decide when to pump, that information comes from your head. The human brain sends special electrical signals to your heart. These small electrical pulses cause the various muscles that make up your heart beat at the right times.
Many dangerous problems with your heart happen when the muscles or something in the links between the brain and your heart get confused. The special first aid treatment with the big paddles and the electrical shock is designed to get the heart muscles back into sync with one another. In one sense it is like hitting a reset button. This special electric shock is designed to reset the timing of your heart's beats, which often fixes at least some of the problems that cause a heart to stop working correctly.
If you are asking about the "spiritual heart" (hence the posting in this section), the role of the "heart" changes from society to society. Some ancient cultures believed that the head was where your "soul" lived. Others believed it was the liver, or other organs. The view that "won the contest" throughout most of the world was that the human heart was the place where human life centered.
