Accepted Answer

The epiglottis is a flap of cartilage located at the base of the tongue. Its main function is to cover the glottis (the opening to the trachea) during swallowing to prevent food or liquid from entering the lungs. When a person is talking, breathing, yawning, or sleeping, the epiglottis does not cover the glottis.
