Across
  1. 2. diaphragm & external intercostal muscles contract & relax causing normal rhythmic breathing
  2. 10. found in larynx & comprised of vocal ligaments covered by mucous membrane
  3. 11. inferior to larynx superior to primary bronchi, anterior to esophagus, supported by C-shaped cartilages
  4. 14. branching of bronchi that lack rings of cartilage & lined with simple columnar or simple squamous epithelium
  5. 15. also known as the voice box, supported by framework of cartilages, ligaments, & muscles, including thyroid, cricoid, & epiglottis cartilages
  6. 19. bronchi, also known as segmental bronchi, that divides into 8 to 10 branches
  7. 20. volume of thoracic cavity decreases, intrapulmonary pressure increases, air flows out of lungs
  8. 21. from end of soft palate to level with hyoid bone
  9. 22. air-filled cavities (sinuses) named after bones in which they reside, communicate with nasal cavity by ducts
  10. 23. opening between vocal folds, air forced through here cause vibration of vocal folds resulting in production of sound
  11. 24. v-shaped anterior projection, also known as Adam's apple
  12. 28. nervous control of respiration located in medulla oblongata of brainstem controlling rate & depth of breathing
  13. 30. vocal folds plus rima glottidis
  14. 31. largest cartilage, located in anterior & lateral wall
  15. 32. branching of primary bronchi, three from right & two from left
  16. 33. anterior border of oropharynx
Down
  1. 1. inferior cartilage to thyroid, completely ring-shaped
  2. 3. spoon-shaped cartilage that projects superiorly into pharynx, swallowing cause it to close the opening of larynx preventing materials from entering lower respiratory tract
  3. 4. also known as breathing, movement of air into & out of respiratory system
  4. 5. left & right paired bronchi that branch from trachea
  5. 6. starts inferior to hyoid bone, continuous with larynx & esophagus
  6. 7. area of body that is shared by digestive & respiratory systems, divided into three regions naso-, oro-, & laryngo-
  7. 8. begins at nostrils & ends as openings to nasopharynx
  8. 9. division of respiratory system into conducting & respiratory
  9. 12. volume of thoracic cavity increases, intrapulmonary pressure decreases, air flows into lungs
  10. 13. openings to nasopharynx, comprised of superior, middle, & inferior portions that condition air within nasal cavity
  11. 16. continuous with nasal cavity & superior to soft palate
  12. 17. division of respiratory system into upper & lower
  13. 18. stimulation that results in bronchoconstriction
  14. 25. divides nasal cavity into right & left portions, forms medial wall of each cavity
  15. 26. opening in lateral walls found in nasopharynx that equalize air pressure in middle ear
  16. 27. stimulation that results in bronchodilation
  17. 29. primary bronchi that is wider & more vertical, foreign particles are more likely to get lodged in here
