PSL 250 FINAL EXAM UPDATED ACTUAL QUESTIONS
AND CORRECT ANSWERS
Question:
1. what are the functions of the respiratory system?
Answer:
- air passageway
- protection
- site for exchange of oxygen and carbon dioxide
- detection of odors
- sound production
Question:
2. air passageway
Answer:
air moves between atmosphere and alveoli as we breathe
Question:
3. protection
Answer:
can trap and destroy foreign particles, macrophages and other immune cells
Question:
4. site for exchange of oxygen and carbon dioxide
Answer:
- oxygen diffuses from alveoli into blood
- carbon dioxide diffuses from blood into alveoli
Question:
5. detection of odors
Answer:
olfactory receptors in superior nasal cavity
Question:
6. sound production
Answer:
- air moves across vocal cords of the larynx (voice box)
- vocal cords vibrate, producing sound
Question:
7. where are the lungs located?
Answer:
thoracic cavity
,Question:
8. general structure of the lungs
Answer:
- each lung has lobes (left = 2, right = 3)
- bronchi/bronchioles
- millions of alveoli
- protected by the ribs
Question:
9. structural vs functional organization of the respiratory system
Answer:
- structural: upper vs lower respiratory tract
- functional: conducting zone (air movement) vs respiratory zone (gas exchange)
Question:
10. upper respiratory tract
Answer:
- nose
- nasal cavity
- pharynx (throat)
- larynx (voice box)
Question:
11. lower respiratory tract
Answer:
- trachea (wind pipe)
- bronchus
- bronchioles
- terminal bronchiole
Question:
12. conducting zone
Answer:
bulk movement of air (nose --> terminal bronchiole)
Question:
13. respiratory zone
Answer:
respiratory bronchiole, alveoli
Question:
14. what is the last part of the URT?
Answer:
larynx
Question:
15. what is the start of the URT?
, Answer:
trachea
Question:
16. what is the end of the conducting zone?
Answer:
terminal
Question:
17. movement of air in the respiratory system
Answer:
1. nose
2. nasal cavity
3. pharynx
4. larynx
5. larynx
6. trachea
7. bronchi
8. bronchioles
9. terminal bronchiole
10. resp bronchiole
11. alveolar duct
12. alveoli
Question:
18. what are common names for the pharynx, larynx, and trachea?
Answer:
- pharynx = throat
- larynx = voice box
- trachea = windpipe
Question:
19. nasal cavity
Answer:
- conditions the air
- warms, cleans, and humidifies the air
Question:
20. nasal cavity anatomical features
Answer:
- boney projections which increase the surface area
- increase contact between air and nasal surface
Question:
21. why does a runny nose (rhinorrhea) occurs?
Answer:
increased production of mucus, cold virus, allergy, exposure to cold air, spicy food
