The Lungs

The human lungs are like sponges inside your chest that help you breathe. They bring oxygen from the air into your body and get rid of carbon dioxide, a waste gas. When you breathe in, your lungs fill up with air, and when you breathe out, they push the air out. The lungs work with your heart to send oxygen through your blood to all your cells. Taking care of your lungs by not smoking, exercising, and breathing clean air helps them stay healthy and strong!
