Which structure prevents food from entering the trachea?

Explanation:
The epiglottis acts as a flap that covers the opening to the trachea during swallowing, preventing food and liquids from entering the airway. When you swallow, the larynx moves upward and the epiglottis folds down to seal the glottic opening, directing the bolus toward the esophagus instead of the trachea. The uvula helps prevent nasal regurgitation as part of the soft palate, not the airway. The trachea is the airway itself, not a structure that blocks food entry. The larynx participates in protecting the airway, but the specific barrier that stops food from entering the trachea is the epiglottis.
