RESPIRATORY SYSTEM FINAL EXAM
QUESTIONS AND ANSWERS
Pulmonary ventilation - answer-breathing of air in/out of lungs
Gas exchange (external respiration) - answer-occurs between air and blood in lungs
Transport of respiratory gases - answer-o2 and co2 are transported between lungs and
body's cells
Gas exchange (internal respiration) - answer-occurs between blood and tissues
Cellular respiration - answer-tissues use oxygen and produce co2 (glucose gets
converted to atp in mitochondria)
Nose - answer-provides airway, moistens and warms air, filters air, aids in speech,
olfactory receptors
Olfactory mucosa - answer-houses smell receptors
Respiratory mucosa - answer-lines majority of nasal cavity
Paranasal sinuses - answer-drain into nasal cavity
Sinusitis - answer-inflammation of paranasal sinuses, caused by viral, bacterial, or
fungal infection
Pharynx - answer-connects nasal cavity and mouth to larynx superiorly and to
esophagus inferiorly; base of skull to 6th vertebrae; has 3 regions
Nasopharynx - answer-posterior to nasal cavity, solely air passageway (uvula,
pharyngeal tonsils)
Uvula - answer-hangs from soft palate, helps prevent food from going up nose
Pharyngeal tonsils (adenoids) - answer-posterior wall of nasal cavity, destroy pathogens
Oropharynx - answer-posterior to oral cavity, from soft palate to epiglottis (fauces,
palatine tonsils, and lingual tonsils)
Fauces - answer-entry way to oropharynx
Palatine tonsils - answer-located in posterior wall of middle portion of pharynx (lateral
walls of fauces)
