Anatomy of the Respiratory System
Across
- 4. act as resonance chambers in speech
- 6. double-layered sac of serous membrane that encloses the lungs
- 7. terminal branches of the respiratory tree
- 11. increase air turbulence,warm and moisten air as it enters the nasal cavity
- 13. bring air from the trachea to the lungs
- 15. false vocal cords
- 18. air passage that is posterior to the nasal cavity
- 19. prevents foreign objects from entering lung with coughing reflex
Down
- 1. divides nostrils
- 2. allows air safely in and out of lungs
- 3. forms a lid over the larynx when we swallow
- 5. air-blood barrier
- 8. posterior separation of the oral and nasal cavities
- 9. shield shaped part of the larynx
- 10. reinforces trachea while allowing esophagus to expand if necessary
- 12. the lungs are divided into five of these, three on the right and two on the left
- 14. anterior separation of the oral and nasal cavities
- 15. vibrate with expelled air for speech
- 16. store air for gas exchange
- 17. air and food passage that is posterior to the oral cavity
