Facts about the Heart
The human heart is a big pump made of muscles that constantly keeps pumping blood throughout our body every moment. It is capable of pumping millions of gallons of blood throughout the body in our lifetime. Our veins help the blood to travel to the heart and the arteries help it to travel away from the heart. This organ is located in the middle of our chest and well-protected by our rib cage. It has four chambers. Two of them are atria and other two are ventricles. The heart and blood vessels together are known as the circulatory system.
