12. The trachea is commonly called the: trachea

13. The Bronchial Tree What part of the respiratory system is this?

14. The passage of oxygen and carbon dioxide between the alveoli and RBC: external respiration

16. The Alveoli What part of the respiratory system is this?

17. A common tube shared by the respiratory and digestive systems. pharynx

19. The Lungs What part of the respiratory system is this?

20. What structure contains the vocal cords? larynx

21. The larynx is commonly called the (1) or the (2) . Voice box Adam’s apple

22. The Pharynx What part of the respiratory system is this?

23. What are the names of the four sinuses? Maxillary Ethmoidal Sphenoidal Frontal

24. These act as “first line” defenders, screening out microorganisms from the air, food, and liquids that enter the body: tonsils

25. How many alveoli do the lungs contain? 300 million

26. The area of the lung where the bronchial tubes, pulmonary artery, pulmonary veins, lymph vessels and nodes, along with aereolar tissue all exist together is called the: root

27. The trachea branches just outside the lungs to form the: Primary bronchi

28. The rings of the trachea are composed of: Hyaline cartilage

29. When chronically inflamed, the pharyngeal tonsils can obstruct the opening to the nasal cavity and are often called: adenoids

30. The smallest bronchial tubes in the lungs are the: bronchioles

31. Where is the oropharynx located? behind the oral cavity (mouth)

32. How many lobes does each lung have? right lung three lobes left lung two lobes

33. Smoking damages what two organs of the body most severely? lungs & heart

34. The small canals running from the ears to the throat are called the: Eustachian or auditory tubes

35. “ Hair-like” structures that constantly beat mucus upwards and help to cleanse the lungs: cilia

36. The organ that most influences the size of the left lung: heart

37. The organ that most influences the size of the right lung: liver

38. The two pathways that properly lead out of the pharynx are: esophagus larynx & trachea

39. The external openings to the respiratory tract that are a part of the external nose are called the ___________________ . nostrils

40. A triangular framework of bone and hyaline cartilage covered with skin and lined internally with mucus membranes is the: external nose

41. The lung’s total air capacity is divided down into “millions” of tiny air sacs. The purpose of this division is: allows for increased surface area for gas exchange.

42. Small chambers or “air sacs” at the end of the bronchioles are called: alveoli

43. The right lung is divided into three lobes. These are the (1) , (2) , and (3) . superior lobe middle lobe inferior lobe

45. Tonsils located in the oropharynx. palatine tonsils

46. Blood vessels that carry freshly oxygenated (red) blood away from the capillary network and back to the heart. Pulmonary veins

47. Tonsils located in the laryngopharynx, at the base of the tongue, are called: Lingual tonsils

48. Tonsils located at the back of the nasal cavity are called the: pharyngeal tonsils

50. oropharynx Subdivision of the pharynx located behind the oral cavity is the:

51. laryngopharynx Subdivision of the pharynx located behind the larynx is the:

52. The inflammation of the paranasal sinuses, usually due to infection or allergy. sinusitis

53. The two lobes of the left lung are the: Superior lobe Inferior lobe

54. Blood vessels that bring deoxygenated (blue) blood from the heart to the capillary network surrounding each alveolus. Pulmonary arteries
