Q6. Why is the right main bronchus more prone to aspiration?
- It lacks cartilage support
- It is more vertical and wider
- It is narrower and longer

Q7. How does the mucociliary escalator function in the trachea?
- Contracts tracheal muscles to expel mucus
- Moves mucus upward via cilia

Q8. Which artery is a major supplier of blood to the thoracic portion of the trachea?
- Subclavian artery
- Superior thyroid artery
- Bronchial arteries
- Pulmonary arteries
Q9. What histological feature distinguishes the trachea from the bronchi?
- Presence of alveoli
