Questions & Answers|Latest2024/2025 Study Guide
1. True or false.
The lungs are symmetrical.: False
2. Hilum: the "root" of the lung
3. healthy lung tissue is what color: peachy/pink color
4. pleurae: membranes that surround the lungs and the cavity around the lungs
5. visceral pleura: layer of pleura that faces/covers the lung
6. parietal pleura: outer layer of pleura lying closer to the ribs and chest wall that
covers the surface around the lungs
7. pleural space/cavity: Space between the visceral and parietal pleural mem-
branes (small)
typically empty but has a small amount of fluid that allows for frictionless breathing
when diseased, this space can fill with air or fluid
8. what is the function of the pleurae: the pleurae help reduce friction and help
with inflation and inhalation
compartmentalize, protect, and lubricate the lungs
9. the three main functions of the respiratory system: 1) air conduction
2) air filtration
3) exchange of gases aka respiration
10. other things respiratory system has roles in: vocalization, sense of smell.
body's pH regulation
11. structures in the respiratory system: nasal cavity, pharynx, larynx, trachea,
bronchi, lungs
12. what happens to air as it goes from outside the body to the lungs: air is
filtered so it has no debris
air is warmed to body temp
air is humidified and becomes saturated with water
13. nasal cavities aka fossae are composed of what: none and cartilage
14. nasal septum: a wall of cartilage that divides the nose into two equal sections
of left and right fossae
15. vestibule: most external part of nasal cavity just inside the nostrils
16. vestibule lining: skin continuation from the face and vissibrae
17. Vibrissae: short thick hairs that help filter for the respiratory tract aka nose hairs
18. nasal conchae or folds: increase the surface area of nasal cavity to aid in
warming and humidification of incoming air
19. why is the nasal cavity highly vascularized: to warm incoming air
20. Three regions of the pharynx: nasopharynx, oropharynx, laryngopharynx
21. nasopharynx: connection between nasal cavity and pharynx - superior region
of the pharynx at the back of the nose and above the soft palate

22. Eustachian tube: connects the middle ear with the nasopharynx and allows
passage of air
23. oropharynx: central portion of the pharynx caudal to the mouth and anterior to
the epiglottis
24. laryngopharynx: inferior part of the pharynx connecting the pharynx to the
opening into the larynx and esophagus
25. what separates the nasal cavity from the oral cavity in the mouth: the hard
and soft palates
26. hard palate: roof of the mouth
27. aspiration: when food or liquid accidentally enters the trachea
may cause pneumonia
28. Pharynx: passageway for food to the esophagus and air to the larynx
29. advantages of shared passageway of the pharynx: 1) air can enter through
the mouth when nasal cavity is obstructed
2) allows for relatively normal breathing while eating
3) greater air intake during heavy exercise that requires more gas exchange
30. soft palate: the muscular posterior portion of the palate that closes off the
nasopharynx during swallowing or speaking
31. glottis: an opening in the larynx where vocal folds are located
32. Larynx: voice box; passageway for air moving from pharynx to trachea; contains
vocal cords
33. vocal folds (true vocal cords): at the edges of the glottis and embedded in
mucous membranes
flexible and pliable bands of connective tissue that vibrate with expelled air to create
sound (speech)
34. single cartilages: thyroid, cricoid, epiglottis
35. epiglottis: a flap of cartilage at the root of the tongue, which is depressed during
swallowing to cover the opening of the windpipe/larynx
36. thyroid cartilage: Adam's apple
larger in males
37. paired cartilages: arytenoid, corniculate, cuneiform
38. expectorate: cough or spit out phlegm from the throat or lungs
39. pneumonia: An inflammation of lung tissue, wherer the alveoli in the affected
areas fill w/fluid
40. Esophagus: A muscular tube that connects the mouth to the stomach.
lies posterior to the larynx and trachea
41. Bronchi: the branches located at the lower end of the trachea that carry air into
the lungs.
