What us a skin flap that covers the larynx to prevent from down the airway?

The skin flap that covers the larynx to prevent food and liquid from entering the airway during swallowing is called the epiglottis. It is a flexible, leaf-shaped structure located at the base of the tongue. When you swallow, the epiglottis folds down to cover the larynx, directing food and liquid into the esophagus instead of the trachea, thus preventing aspiration and protecting the airway.
