What is the function of the epiglottis when swallowing?

During swallowing, the epiglottis acts as a protective flap that covers the opening of the larynx. As you swallow, the larynx elevates and the epiglottis tilts backward to sit over the glottis, directing the bolus into the esophagus and preventing liquids or solids from entering the airway. This is how it prevents aspiration. It doesn’t produce vocal sounds—that comes from the vocal cords in the larynx. It also doesn’t filter air—that job is done by the nasal passages and other airway structures. And it doesn’t keep the airway open during swallowing; it closes briefly to guard the airway while you swallow.
