The story
Quarky gets breathed in to discover the two great balloons that swap fresh air for waste, thousands of times a day.
What you'll learn

- A dome-shaped muscle, the diaphragm, makes air rush in.
- Oxygen slips from tiny air sacs into your blood.
- Your lungs also power your voice when you talk and sing.
