After passing through the glottis, inspired air travels to where next?.

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.

Choice A rationale:

While the spleen is the body’s largest lymphatic organ, this statement does not encompass all of its functions.

Choice B rationale:

The spleen does contribute to the production of white blood cells, but this is not its only function.

Choice C rationale:

The spleen does play a role in immunity, but it has other functions as well.

Choice D rationale:

This choice accurately describes the multiple functions of the spleen, including immunity, destruction of old red blood cells, blood storage, and hematopoiesis.
