One of the reasons why some people cough while eating a meal may be due to the improper movement of _______ :
Correct answer: C. Epiglottis
- A. Larynx
- B. Diaphram
- C. Epiglottis
- D. None of these
Explanation
The epiglottis is a flap that covers the opening of the larynx during swallowing and directs food into the oesophagus. If it moves improperly, food may enter the airway and trigger coughing; students may choose the larynx because it is the airway structure involved, but the protective flap is the epiglottis.
