The heart pumps oxygen-rich blood to the body and lungs.
Your heart is a special muscle inside your chest that pumps blood through your body. A muscle is a body part that can squeeze and relax to make things move. Your heart is about the size of your fist. It works like a pump that never stops, beating all day and all night, even when you are sleeping.
Every time your heart beats, it does two important jobs. First, it pushes blood out to every part of your body. This blood carries oxygen, which is a gas from the air that your body needs to stay alive and work properly. Second, your heart pulls blood back in so it can pump it out again. You can feel your heartbeat by placing your hand on your chest. That thump-thump feeling is your heart squeezing and relaxing over and over.
Your heart beats faster when you run, jump, or play because your body needs more oxygen during exercise. Exercise is any activity that makes your body work harder than usual. When you are resting or sitting quietly, your heart beats more slowly because your body does not need as much oxygen. Your heart is always working to keep you healthy and strong.
Interesting Fact: Your heart beats about 100,000 times every single day! That means it will beat more than 3 billion times during your entire life.
