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