Which of the following is a function of the nasopharynx?.
Warm and moisten inspired air.
Filter dust.
Provide openings for the right and left Eustachian tubes.
Contain olfactory receptors responsible for the sense of smell.
The Correct Answer is C
Choice A rationale:
While the nasopharynx does play a role in warming and moistening inspired air, this is not its primary function.
Choice B rationale:
The nasopharynx does not primarily filter dust. This function is mainly performed by the nasal cavity and the hairs within the nostrils.
Choice C rationale:
The nasopharynx provides openings for the right and left Eustachian tubes. These tubes connect the middle ear to the nasopharynx and help equalize air pressure on either side of the eardrum.
Choice D rationale:
The nasopharynx does not contain olfactory receptors responsible for the sense of smell. These receptors are located in the nasal cavity.

Correct Answer is ["A","B","C"]
Explanation
Choice A rationale:
Sinuses are indeed air-filled cavities. They are hollow spaces in the skull and the face bones around your nose.
Choice B rationale:
Sinuses are located in the skull and around the nose. There are four pairs of sinuses, named for the bones that they’re located in.
Choice C rationale:
One of the functions of the sinuses is to help lighten the head. The air-filled cavities provide a sort of crumple zone that can absorb impact and protect the brain.
Choice D rationale:
Gas exchange does not occur in the sinuses. The primary function of the sinuses is to produce mucus that moistens the inside of the nose. This mucus layer serves to trap dust and other particles that might otherwise reach the lungs.
Choice E rationale:
The sinuses do not directly help with hearing. The structures that are primarily responsible for hearing are the ears, specifically the eardrums and the bones of the middle ear. So, the correct answers are Choices A, B, and C, after analyzing all choices. .
Correct Answer is D
Explanation
Choice A rationale:
The glottis is the space between the vocal cords and does not direct food and liquids into the esophagus during swallowing.
Choice B rationale:
The Adam’s apple, also known as the thyroid cartilage, is a structure in the neck and does not direct food and liquids into the esophagus during swallowing.
Choice C rationale:
The conchae are structures in the nasal cavity and do not direct food and liquids into the esophagus during swallowing.
Choice D rationale:
The epiglottis is responsible for directing food and liquids into the esophagus during swallowing. It acts as a lid over the windpipe, preventing food from entering the lungs.
