Question

What structure aids in food moving down the esophagus and not the trachea?

1) Epiglottis
2) Larynx
3) Pharynx
4) Trachea

Answer 1

The epiglottis aids in food moving down the esophagus and not the trachea by blocking access to the trachea during swallowing.

Step-by-step explanation:

The structure that aids in food moving down the esophagus and not the trachea is the epiglottis.

During swallowing, the epiglottis folds over the glottis, which is the opening to the larynx, effectively blocking access to the trachea.

This process ensures that food enters the esophagus and not the trachea, preventing choking.
