What is the function of the bronchi and bronchioles in the lungs?
What is the function of the bronchi and bronchioles in the lungs?
- To facilitate the exchange of gases

Why are alveoli important for gaseous exchange?
Why are alveoli important for gaseous exchange?
- Because they contain oxygen-rich air
- Because they are surrounded by a dense network of capillaries (correct)
- Because they provide a small surface area for gaseous exchange
