How the Lungs Work
Your child can follow the air we breathe. It goes down the windpipe, splits into smaller tubes, and reaches tiny sacs. There, oxygen swaps into the blood.
In curriculum terms
Explain how the respiratory system works in detail: air travels through the nose/mouth, down the trachea, into bronchi and bronchioles, reaching tiny air sacs (alveoli) in the lungs where oxygen passes into the blood and carbon dioxide passes out
