What is this?
Your lungs are like two squishy, balloon-like organs inside your chest that help you breathe. They work hard to take oxygen from the air you breathe in and put it into your blood, and then get rid of waste gas when you breathe out. This model helps us see the big differences between lungs that are healthy and lungs that have been damaged by smoking.
