Your heart is a very important part of your body! It pumps blood aound the body through blood vessels. Think of it as the car engine for your body. It is important to pump blood around the body because the blood carries Oxygen, glucose (energy for the body), and other very important cells like white blood cells!
When the heart beats, it pumps blood out and pumps blood into the heart. This action happens millions of times in a day because our body constantly needs the cells and things in blood to function! The heart takes in newly made blood from bones and transports or pumps it out to the rest of the body. The heart is a very important part of our body and is our main engine!!
