"What happens when you take a deep breathe? Woosh! Air rushes into your lungs. Your lungs help you get the air you need to live. They work with your heart to send oxygen around your body and get rid of waste you don't want. And that's not all! Explore what's inside you with fun text, bright pictures, and lively illustrations"--
