Damage to the cribriform plate of the ethmoid bone would MOST directly impair: Air warming Sense of smell Speech resonance Mucus Production None 2. Which structure forms the posterior bony part of the nasal septum? Nasal bone Perpendicular plate of ethmoid and vomer Hyaline cartilage Palatine bone None 3. The nasolacrimal ducts drain tears into the: Frontal sinuses Nasal cavity Pharynx Conjunctival sacs None 4. During nasal filtration, synchronous cilia beating moves contaminated mucus toward the: Anterior nares Pharynx Sinuses Epiglottis None 5. The epiglottis is anchored directly to the: Thyroid cartilage Cricoid cartilage Hyoid bone Arytenoid cartilage None 6. Vocal cord adduction (closure) would PRIMARILY: Facilitate breathing Enable sound production Protect the trachea Open the laryngeal inlet None 7. The incomplete posterior tracheal rings are closed by: Hyaline cartilage Smooth muscle and connective tissue Fibrocartilage Parietal pleura None 8. Foreign bodies are more likely to lodge in the right bronchus due to its: Longer length More vertical orientation Narrower diameter Fewer cartilage rings None 9. Bronchioles lack cartilage, resulting in: Rigid airways Thicker smooth muscle walls Ciliated epithelium loss Increased mucus production None 10. Surfactant deficiency in premature newborns primarily causes: Reduced mucus clearance Alveolar collapse during expiration Impaired gas exchange membrane Bronchoconstriction None 11. The pulmonary arteries carry: Deoxygenated blood Oxygenated blood Lymphatic fluid Surfactant None 12. During diaphragm contraction, the central tendon moves: Superiorly Inferiorly Anteriorly Laterally None 13. The visceral pleura is directly attached to the: Chest wall Lung surface Diaphragm Mediastinum None 14. Pneumothorax (air in pleural cavity) causes lung collapse due to: Infection Loss of negative pressure Vascular damage Bronchial obstruction None 15. Gas exchange occurs DIRECTLY between: Bronchioles and arteries Alveoli and capillaries Trachea and veins Pleura and lymphatics None 16. Which structure is NOT found in the mediastinum? Trachea Heart Lung lobes Esophagus None 17. Stimulation of the vagus nerve would cause: Bronchodilation Bronchoconstriction Increased surfactant Diaphragm relaxation None 18. The phrenic nerve directly innervates the: Larynx Diaphragm Intercostal muscles Bronchioles None 19. The carina marks the bifurcation of the: Larynx Trachea Pharynx Bronchioles None 20. Which lung surface contacts the ribs? Medial Costal Basal Hilum None 21. The left lung has fewer lobes than the right primarily due to: Smaller size Cardiac impression Diaphragm shape Vascular supply None 22. Paranasal sinuses communicate with the nasal cavity via: Nasolacrimal ducts Small openings Posterior nares Pharyngeal tonsils None 23. During swallowing, the larynx is protected by: Vocal cord vibration Epiglottic closure Cricoid contraction Thyroid elevation None 24. The "Adam's apple" is formed by the: Cricoid cartilage Thyroid cartilage Epiglottis Hyoid bone None 25. Terminal bronchioles lead directly into: Alveolar ducts Respiratory bronchioles Segmental bronchi Trachea None 1 out of 3 Thanks For Submitting Your Quiz !!
