Which of the following is true about the sinuses? Select all that apply.
(Select All that Apply.).

hoice A rationale:

Inspired gas passes through the convoluted air passages of the nasopharynx and pharynx which generates turbulence. This turbulence increases evaporative heat exchange between the air and the mucosa. The nasal mucosa is the lining of the nasal cavity. It moistens air that is coming into the body during inhalation.

Choice B rationale:

The sphenoid is a bone located within the skull and does not directly contribute to the heating and humidification of air.

Choice C rationale:

The nasopharynx is part of the pharynx, located above the soft palate. It serves as an air passage way connecting the nasal cavity to the throat and does not directly heat or humidify the air.

Choice D rationale:

The oropharynx is also part of the pharynx, located between the soft palate and the epiglottis. It serves as a passageway for both air and food but does not directly heat or humidify the air.

Choice A rationale:

Inhaled food or foreign objects are most likely to lodge in the right bronchus because it is wider and more vertical than the left.

Choice B rationale:

While it is possible for objects to lodge in the left bronchus, it is less common due to its narrower and less vertical structure.

Choice C rationale:

Bronchioles are smaller structures within the respiratory system where foreign objects are less likely to lodge.

Choice D rationale:

The pharynx is not the most common location for inhaled food or foreign objects to lodge.
