The circulatory system pumps blood through the heart. The constant beating you feel when you put your hand over your chest is literally your heart pumping blood through your veins. The reason it does this is to get oxygen to your brain, Red blood cells (Ironically blue at this point) pass through your body for various reasons and pump through your lungs picking up oxygen from the lungs (which then turns them red) and on up into the brain which allows us to live… yay! Bottom line, heart pumps blood to keep the brain alive. HOW it pumps blood is hard to explain. Just think of like a turkey baster, pump the end and it comes out? Can't think of putting it any easier.
