The epiglottis is a flexible flap at the superior end of the larynx in the throat. It acts as a switch between the larynx and the esophagus to permit air to enter the airway to the lungs and food to pass into the gastrointestinal tract.hroughout each day, the epiglottis spends the vast majority of its time relaxed at the superior edge of the larynx just posterior to the tongue. In this position, air is able to enter the pharynx from the nose or mouth and pass freely into the larynx and onward to the lungs.
