This is what your heart looks like:

Your heart is made of muscle similar to the muscle found in other parts of your body. It is the strongest muscle in your body.

It is also a very unique and special muscle. You never have to think to make it work. Your heart never stops working, even when you sleep your heart continues to beat. Your heart has a very special job. It pumps blood from your head to your toes and back again in blood vessels that can circle the world two times! In one day, your heart will beat over 100,000 times.
