Breathe deeply. Then you’ll really feel your lungs at work – they’re like two plastic bags that fill up with air when we breathe in. The air has oxygen in it that we need to stay alive.
The lungs help you to breath in new air, and get rid of old air when we breathe out. The air that we breathe out has carbon dioxide in it that we want to get rid of. Our lungs are one of the biggest organs you have and they’re very important – they even help you to talk and sing!
Did you know?
We breathe in (inhale) air about 20 times in a minute – that’s a lot of air!
