Lung Histology MCQs: practice questions

Sample Lung Histology multiple-choice questions from Respiratory Histology.

A lung section shows an airway with no cartilage or glands and a prominent smooth-muscle layer. Which structure is most likely?
- A. Bronchiole
- B. Bronchus
- C. Trachea
- D. Larynx
- E. Alveolar sac
Which structure contains respiratory bronchioles, alveolar ducts, alveolar sacs, and alveoli?
- A. Respiratory portion
- B. Conducting portion
- C. Upper airway only
- D. Larynx
- E. Trachea
Which combination best describes lung histology?
- A. The entire lung is lined by stratified squamous epithelium
- B. All airways contain cartilage
- C. Gas exchange occurs mainly in the trachea
- D. Alveoli contain thick smooth-muscle walls
- E. Conducting airways transition to respiratory units containing thin alveoli and dense capillary networks
Which structure connects respiratory bronchioles with alveolar sacs?
- A. Terminal bronchioles
- B. Tracheal rings
- C. Bronchi
- D. Laryngeal folds
- E. Alveolar ducts
Which airway is lined mainly by simple cuboidal epithelium and lacks cartilage?
- A. Trachea
- B. Large bronchus
- C. Bronchiole
- D. Larynx
- E. Main bronchus
Which airway is the final conducting airway?
A lung section shows cartilage plates surrounding an airway. Which region is this most likely?
Which pulmonary structure is composed of multiple alveoli opening into a common passage?
Which structure is specialized for conditioning inspired air before gas exchange?
Which pulmonary cell removes inhaled particles from alveolar spaces?
The conducting portion of the respiratory system primarily:
Which vessels return oxygenated blood from the lungs to the heart?
The visceral pleura is lined by:
Which lung connective-tissue structure surrounds the conducting and respiratory units and carries vessels and nerves?
Which pulmonary structure provides the largest surface area for gas exchange?
Which structure is the main site of pulmonary gas exchange?
Which pulmonary cell secretes surfactant?
The respiratory portion of the lung begins with the:
Which pulmonary component carries deoxygenated blood toward the alveolar capillary bed?
Which feature distinguishes the respiratory portion from the conducting portion?
Which cell type predominates in the epithelial surface of alveoli?
Which structure is covered by visceral pleura?
Which feature is typical of the pulmonary interalveolar septum?
Which component is present in the walls of bronchi but absent from bronchioles?
Which lung structure is directly involved in maintaining the low-resistance path from terminal bronchioles to alveoli?
