Correct Answer is A
Explanation
Answer and explanation
The correct answer is Choice A.
Choice A rationale:
The conchae or turbinates are structures in the nasal cavity that increase the surface area of the mucosa exposed to the air. As air passes over the mucosa, it picks up moisture and heat, which helps to humidify and warm the air before it reaches the lungs.
Choice B rationale:
The sphenoid is a bone located at the base of the skull. It does not have a direct role in the heating or humidification of air.
Choice C rationale:
The nasopharynx is part of the pharynx that connects the nasal cavity to the throat. While it does play a role in the passage of air from the nose to the lungs, it is not the primary site where air picks up moisture and heat.
Choice D rationale:
The oropharynx is another part of the pharynx, located below the nasopharynx. It is involved in both respiratory and digestive processes, but it is not the main site where air picks up moisture and heat.
So, the correct answer is Choice A, after analyzing all choices.
