| 1. | The branched areas in the lungs are blood vessels and bronchi.
|
| 2. | Unlike asthma, hypersensitivity pneumonitis targets lung alveoli rather than bronchi.
|
| 3. | Muscle spasm and inflammation within the bronchi get worse this narrowing.
|
| 4. | The respiratory tract begins with the trachea and bronchi.
|
| 5. | In contrast to emphysema, asthma affects the bronchi, not the alveoli.
|
| 6. | The bronchi branch off into smaller sections inside the lungs, called bronchioles.
|
| 7. | The main bronchi have relatively large lumens that are lined by respiratory epithelium.
|
| 8. | Hyaline cartilage is present in the bronchi, surrounding the smooth muscle layer.
|
| 9. | These plates give structural support to the bronchi and keep the airway open.
|
| 10. | They lay eggs into the airways ( bronchi ).
