What is the function of the epiglottis during the swallowing process?

The function of the epiglottis during the swallowing process is to close over the top of the larynx. This structure is a flap of cartilage located at the root of the tongue, and it plays a crucial role in protecting the airway during swallowing. When you swallow, the epiglottis folds down to cover the glottis, which is the opening of the larynx, thus preventing food or liquids from entering the trachea and directing them into the esophagus instead. This action is essential for preventing choking and ensuring that only air enters the trachea during respiration.
