Across
- 5. connects the nasal cavity and the mouth superiorly to the larynx esophagus
- 6. oxygen moves from the lungs to the blood and carbon dioxide moves from the blood to the lungs.
- 8. Less that 0.5 mm in diameter, feed into respiratory bronchioles
- 10. covers the external surface of the lung
- 12. An active process that occurs from contracting abdominal and oblique muscles. This process is of importance when control of expired air is needed for activities like vocalizations.
- 19. nose and sinuses work together to provide a passageway for air to enter the internal respiratory structures
- 21. as the amount of air pushed into and out of the lung as a result of inspiration and expiration.
- 23. Guides air and food to the appropriate channels; continuous with the trachea, known as the voice box
- 24. skeletal muscle that contracts to stimulate inhalation and exhalation
- 27. 3 on the right, 2 on the left
- 28. Cartilage based flap that separates the larynx and lower respiratory tract from the esophagus aka "guardian of the airway"
- 29. Collapsed lung. It results from the loss of negative pressure between the lung and pleural cavity.
- 31. is known as the total amount of exchangeable air, so TV + IRV + ERV.
- 32. oxygen moves from the blood to the cells and carbon dioxide moves from the cells to the blood.
- 33. exchange of gasses into and out of the lungs
- 34. P1V1=P2V2
- 36. The pressure within the pleural cavity. It is always slightly less (by about 4 mm Hg) than the intrapulmonary pressure
- 37. a combination of the different volumes described above
- 38. Inhaled irritants lead to chronic production of excessive mucus. The mucosae of the lower respiratory passageways become inflamed and fibrosed.
- 39. volume of air during quiet breathing
- 41. covers the thoracic wall and the superior portion of the diaphragm
- 42. Achieved when the atmospheric is greater than the intrapulmonary pressure.
- 43. The pressure within the lung, specifically the alveoli (the site of gas exchange).
- 44. amount of air that can be expelled after a tidal expiration.
- 45. nasal cavity, nasopharynx, oropharynx, laryngopharynx, larynx
Down
- 1. larynx, trachea, bronchial tree, alveoli, lungs, pleurae
- 2. amount of air forcibly inhaled above TV
- 3. Passages less that 1mm diameter; lead to terminal bronchioles
- 4. combines all the lung volumes
- 7. exchange gasses with capillary system
- 9. located at the T7 vertebrae
- 11. amount of air that remains in the lung after all expiratory effort. Helps prevent lung and alveolar collapse.
- 13. Windpipe; made of rings of hyaline cartilage
- 14. unexpected death of an apparently healthy infant during sleep. Commonly called crib death
- 15. a dangerous lung condition that can develop after severe illness or injury to the body. Neutrophils leave the body’s capillaries in large numbers and then secret chemicals that increase capillary permeability. The capillary-rich lungs are affected. As the lungs fill with fluid, the patient suffocates.
- 16. space between the parietal and visceral pleura which is filled with fluid
- 17. Feed into alveolar sacs
- 18. obstruction of the pulmonary artery or one of its branches by an embolus (most often a blood clot that has been carried from the lower limbs and through the right side of the heart into the pulmonary circulation)
- 20. two lobes, right lung: 3 lobes because heart takes up more space left of the sternum
- 22. Produce mucus and fluid
- 25. warms, moistens, and filters air
- 26. forms a thin, double layered serosa (outer lining of organs and body cavities)
- 30. occurs when the intrapulmonary pressure is slightly higher than the atmospheric pressure
- 35. the original device used to measure lung capacity and volume
- 40. infectious inflammation of the lungs, in which fluid accumulates in the alveoli; the eighth most common cause of death in the US
