- B. Pneumocyte II
- C. Chondrocyte
- D. Club cell
- E. Neutrophil
Which sequence correctly describes distal airway organization?
- A. Bronchiole → bronchus → alveolus → trachea
- B. Trachea → alveolus → bronchus → bronchiole
- C. Terminal bronchiole → bronchus → respiratory bronchiole → trachea
- D. Alveolus → trachea → bronchus → bronchiole
- E. Bronchus → bronchiole → terminal bronchiole → respiratory bronchiole
Which feature indicates that an airway is part of the respiratory rather than purely conducting portion?
- A. Presence of cartilage
- B. Presence of goblet cells only
- C. Presence of a basement membrane
- D. Alveoli opening from its wall
- E. Presence of smooth muscle
Which epithelium is expected in a larger intrapulmonary bronchus?
- A. Simple squamous
- B. Pseudostratified ciliated columnar
- C. Stratified keratinized squamous
- D. Transitional
- E. Simple cuboidal only
Which structural feature distinguishes bronchi from bronchioles?
- A. Bronchioles contain large cartilage rings
- B. Bronchi lack smooth muscle
- C. Bronchi contain cartilage plates
- D. Bronchioles have alveolar cartilage
- E. Bronchi have no epithelium

What is the major histologic change as bronchi become bronchioles?
As airways become smaller, the respiratory epithelium generally changes from pseudostratified toward:
Which airway is considered the final purely conducting portion of the respiratory tree?
Which airway structure has a continuous layer of smooth muscle surrounding the lumen but no cartilage?
Which feature is absent from terminal bronchioles?
A biopsy shows cartilage plates, smooth muscle, and respiratory epithelium. Which structure is most likely?
Which structure marks the beginning of the respiratory portion of the airway?
Which airway structure has the greatest relative influence on airway resistance because of its smooth-muscle tone?
