Across
- 7. air sac in the lungs
- 11. amount of air remaining in lungs after force expiration
- 14. opening on the lung's medial surface through which primary bronchi and pulmonary blood vessels pass
- 15. lipoprotein secreted by alveolar cells that decreases surface tension of the fluid lining the alveoli permitting expansion
- 16. link between the microbiota of the gut and that of the lung that influences health
- 19. portion of the respiratory tract that carries air through the neck and upper chest
- 22. serous membrane covering the lungs and the thoracic cavity
- 23. the uppermost cartilage of the larynx that closes during swallowing to direct food and liquids to the esophagus
- 24. the pressure between the visceral and parietal pluerae which assists with lung expansion
- 25. the movement of air into and out of the lungs
- 27. the number of oxygen molecules bound to hemoglobin at any one time
- 30. cartilaginous ride situated where the trachea divides into two bronchi
- 31. air that normally remains in conducting airways during respiration
- 32. potential space between the visceral and parietal pleurae
- 33. part of the pharynx residing between the soft palate and the base of the tongue
- 34. part of the pharynx that passes dorsal to the larynx and connects to the esophagus
Down
- 1. the amount of air inhaled and exhaled during quiet breathing
- 2. membrane consisting of alveolar epithelium and capillary epithelium across which gas exchange occurs
- 3. combination of hemoglobin with oxygen
- 4. the maximum amount of air the lungs can contain; vital capacity plus residual volume
- 5. the amount of air inhaled using maximum effort after a normal inspiration
- 6. the contribution of a single gas in a mixture of gases toward the total pressure of the gas mixture
- 8. structure made of cartilage and muscle at the upper end of the trachea that is part of the airway and vocal apparatus
- 9. the amount of air that can be exhaled after normal expiration using maximum effort
- 10. the balance between the amount of air flowing into the alveolus with the flow of blood through the capillaries
- 12. includes all air in the conducting airways plus the air in the alveoli that are poorly perfused
- 13. one of the smaller subdivisions of the bronchial tubes
- 17. the amount of air that can be inhaled and exhaled with the deepest possible breath
- 18. combination of hemoglobin with carbon dioxide
- 20. the opening between the vocal cords
- 21. clusters of alveoli residing at the termination of alveolar ducts
- 26. muscular tube behind the oral and nasal cavities commonly called the throat
- 28. the two main branches leading from the trachea to the lungs that serve as passageways for air
- 29. upper part of the pharynx extending from the posterior nares to the soft palate
- 32. bony structure separating the mouth from the nasal cavity
