Question

which of the following is not a function of the mucus - lined nasal passages at or below normal body temperature?
multiple choice
moistening inspired air
warming inspired air
cooling exhaled air
trapping small particles

Explanation:

The mucus - lined nasal passages moisten inspired air (mucus has water content), warm inspired air (blood vessels in the nasal mucosa can transfer heat), and trap small particles (mucus is sticky). Cooling exhaled air is not a function at or below normal body temperature. When air is exhaled, the nasal passages at normal or below - normal body temperature do not have a significant cooling effect on exhaled air. The cooling of exhaled air is more relevant in some animals in hot environments (e.g., dogs panting) but not a typical function of human nasal passages at or below normal body temperature.

Answer:

Cooling exhaled air
