1. Which of the following describes the diffusion of O2 into the bloodstream and
the diffusion of CO2 out of the bloodstream?: gas exchange
2. Cells needs a constant supply of oxygen to generate energy to drive cellular
activities, creating CO2 as a waste product. (T/F): true
3. Which of the following terms describes the production of speech and melody
created by the vibration of the vocal folds?: vocalization
4. What is the function of the conchae in the nasal cavity?: increase surface area
5. What is the function of the nose in the respiratory system?: sensing odors
6. Which tonsils are located in the posterior wall of the nasopharynx?: pharyngeal
7. What is a function of the paranasal sinuses?: add resonance to speech
8. Where are the pharyngeal tonsils (adenoid) located?: nasopharynx
9. Which statement is true about the oropharynx?: it carries both food and air
10. Where are the palatine and lingual tonsils located?: oropharynx
11. What is an elastic, flexible cartilage in the larynx?: epiglottic cartilage
12. Which structure is not a part of the throat?: larynx
13. Which of the following structures maintains equal air pressure in the lung?-
: alveolar pores
14. Which of the following cell types removes debris from the alveolar wall?: alve-
olar macrophages
15. What leads to carbaminohemoglobin formation?: CO2 + Hb
16. What is the role off the diaphragm during normal breathing?: during inhalation it
contracts and flattens

BRAINSCAPE1
, BRAINSCAPE1
: when volume increases, pressure decreases at a constant temperature
18. What is the function of the aortic body?: it monitors the partial pressure of carbon dioxide,
oxygen, and pH in the blood
19. What is the function of arteries?: they carry blood away from the heart
20. How do temperature and pH affect hemoglobin oxygen saturation?: higher
temperature and lower pH promote the dissociation of hemoglobin and oxygen
