Which of the following is not one of the openings that must be blocked when food moves from the pharynx into the esophagus?
Oropharynx
Nasopharynx
Larynx
Mouth
The Correct Answer is C
A. Oropharynx: The oropharynx is the middle part of the throat behind the mouth. It is the primary pathway food must travel through to reach the esophagus; therefore, it cannot be blocked during swallowing.
B. Nasopharynx: This must be blocked by the soft palate and uvula to prevent food and liquids from entering the nasal cavity.
C. Larynx: The larynx must be blocked by the epiglottis to prevent food from entering the "windpipe" and causing choking.
D. Mouth: The tongue blocks the front of the mouth during the "oral stage" of swallowing to ensure food moves backward into the throat rather than forward out of the lips.
