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