|
Definition
| smaller bronchi which branch then into smaller bronchioles |
|
|
Term
|
Definition
| yes the smooth muscle can contract. like kids with azhma (wheezing lower airway) |

|
Definition
| where they get smaller and smaller then leads to alveoli |
|
|
Term
|
Definition
| they are small sacs that are surrounded by elastic fibers. they allow air pressure throughout the lungs to be equal |
