Across
- 2. these represent the transition from a single conduction pathway of the upper airways into learge surface area required for gas exchange
- 3. the vestibule is lined with what kind of epithelium?
- 4. the opening into the larynx where the vocal folds are located
- 7. the connection between the nasal cavity and the pharynx (above the soft palate)
- 10. the epiglottis, cricoid cartilage, and thyroid cartilage are known as what kind of cartilages?
- 15. the bronchioles, alveolar ducts, alveolar sacs, and alveoli are part of this portion of the respiratory system
- 17. the pharynx is protected by what kind of epithelium?
- 19. the nostrils, trachea, and bronchi are part of this portion of the respiratory system
- 20. which cartilage is known as the adams apple?
- 24. the arytenoid, corniculate, and cuniform are known as what kind of cartilages?
- 25. to warm the air, the nasal cavity is highly _____, which is why nose bleeds are common
- 26. this is what separates the right and left part of the nasal cavity
- 27. other than the vocal fold area, the _____ is lined with typical epithelium
- 29. the lungs are assymmetric due to the position of this, which is situated slightly to the left of the median plane
- 31. the root of the lung, where pulmonary vessels and bronchi enter each lung
- 32. the most external portion of the nasal cavity just inside the nostrils
- 33. the smallest air conducting bronchiole
- 34. the part of the pharynx that is posterior to the mouth and anterior to the epiglottis
Down
- 1. the nostril, pharynx, larynx, trachea, paired main bronchi, and bronchioles are part of this portion of the respiratory system
- 5. where the respiratory bronchioles terminate, also known as the blood-air barrier
- 6. these form the interface between the conducting and respiratory portions of the respiratory system
- 8. the luminal surface of the trachea is lined by what kind of epithelium?
- 9. the type of bronchioles that are the transitional zone in the respiratory system concerned with both air conduction and gas exchange
- 11. the color of a healthy lung
- 12. the part of the pharynx that the pharynx, larynx, and esophagus meet
- 13. this kind of pleurae covers the surfaces surrounding the lungs (ribcage, diaphragm, mediastinum)
- 14. the hard and soft palate separate the nasal cavity from the ____
- 16. this kind of pleurae cover the lungs directly
- 18. these are found in the vestibule and are short and thick hairs that act as a screening device for the respiratory tract
- 21. flexible, pliable bands of connective tissue that vibrate and produce sound when air is expelled past them through the glottis and larynx
- 22. this is formed between the pleurae and is normally empty. it serves to reduce friction and provide a negative pressure environment for lung inflation
- 23. folds that increase the surface area in the nasal cavity for the air to be warmed and humidified
- 28. this occurs when food or liquid accidentally enters the trachea
- 30. the study of organs and structures of the human body visible to the naked eye
