What prevents swallowed food from entering the airways?

The valves created by the false and true vocal folds and the epiglottis prevent food from entering the airway during swallowing. The feeding and respiratory systems share a portion of the pharynx between the area behind the tongue and the area at the entrance to the larynx and the entrance to the esophagus.
