Answer : If I could shrink and travel inside my lungs, I would see two big, pink, spongy bags that look like soft balloons. They are tucked safely behind my ribs in my chest. As I watch, the lungs grow bigger when I breathe in, filling up with air like a balloon getting ready to fly. The air brings oxygen, which is like a superpower that helps my body run, jump, and play. When I breathe out, the lungs shrink back, pushing out a gas called carbon dioxide that my body doesn’t need. Tiny tubes like straws carry the air in and out, and the lungs are always busy, working like a quiet team to keep me alive and strong!
