Question

Which of the following portions of the pharynx is a passage for air only (not food)?
A)Oropharynx
B)Sinopharynx
C)Nasopharynx
D)Laryngopharynx
E)None of the portions of the pharynx is a passageway for only air; all portions transport both air and food.

Accepted Answer

The nasopharynx is the upper portion of the pharynx and is a passageway for air only, as it sits above the soft palate and is not connected to the oral cavity where food enters. The oropharynx and laryngopharynx are both passageways for both food and air, while the sinopharynx is not a recognized portion of the pharynx.
