Your breathing machine!
Your lungs are like two big air baggies inside your chest!
When you breathe in, your lungs fill up with air - like blowing up a balloon!
When you breathe out, the air goes back out - like letting air out of a balloon!
But here's the magic: inside your lungs, there's oxygen that goes INTO your blood!
In the Air: Oxygen (O2) - the good stuff your body needs!
Out the Air: Carbon Dioxide (CO2) - the "used up" air your body doesn't need!
Your lungs are like a trading post: they take oxygen FROM the air and give back carbon dioxide TO the air!
🫁 Oxygen: Your body needs it to make energy - like gas for a car!
💨 Carbon Dioxide: Your cells make this as waste - and you breathe it out!
