1. How many lobes does the left human lung have?: Two lobes 2. Air (not food) pass in which one of the following areas A. Esophagus B. Nasopharynx C. Oropharynx D. Both A. and C.: B. Nasopharynx 3. Rings of cartilage line much of the respiratory tract. In which of one of the following would cartilage NOT be found? A. Trachea B. Larynx C. Bronchi D. Alveoli: D. Alveoli 4. True/false: during inhalation the diaphragm contracts to pull lungs open: - True 5. True/false: Negative pressure is used to move air into the lungs: True 6. True/false: during inhalation the rib cage lifts in an upward motion to open and expand the lungs: True 7. True/false: as the thoracic cavity expands and lung volume increases, the density of the gases filling the lungs increases: False 8. True/false: when the diaphragm rises, thoracic pressure increases and air naturally flows out of the lungs: True (air naturally flows out of the lungs because of the pressure difference) 9. Which cells are most abundant within the alveoli?: macrophages 10. True/false: the fossae is another name for the pleural cavities: False 11. Boyles law states that gas volume is:: Inversely proportional to pressure 12. Which one of the following tracheal cartilages are paired?: Arytenoid 13. Which one of the following is not true of the pleurae?: Visceral pleurae cover the diaphragm 14. Which one of the following is not true of the respiratory physiology?: Tidal volume is the maximum amount of air able to be inhaled beyond normal inhalation 15. Which one of the following is true of the respiratory physiology calcula- tions? A. Vital Capacity (VC) =TLC + RV B. Total Lung Capacity (TLC) =IRV + TV C. Inspiratory Capacity (IC) = TV- IRV D. Functional Residual Capacity (FRC) = RV+ERV: D. Functional Residual Ca- pacity (FRC) = RV+ERV 16. True/false: the gas-exchange region in the lungs must be dry, thin and large: False (requires moisture) 17. True/false: the vestibule is the most external portion of the nasal cavity: - True 18. True/false: the vestibule is lined with typical respiratory epithelium: False (stratified squamous epithelium is found in the vestibule) 19. True/false: because of diffusion, oxygen naturally moves out of the blood into the lungs: False 20. True/false: the bronchioles are surrounded by capillaries for gas exchange- : False 21. The pleural space fills with air, pus or blood A. Pleurisy B. Pulmonary edema C. Emphysema D. Cystic fibrosis: A. Pleurisy 22. This condition results from fluid-filled alveoli A. Pleurisy B. Pulmonary edema C. Emphysema D. Cystic fibrosis: B. Pulmonary edema 23. This condition results in a loss of alveoli A. Pleurisy B. Pulmonary edema C. Emphysema D. Cystic fibrosis: C. Emphysema 24. This hereditary illness results in excess mucus A. Pleurisy B. Pulmonary edema C. Emphysema D. Cystic fibrosis: D. Cystic fibrosis 25. From widest to
