The epiglottis is a flap of cartilage located at the base of the tongue. During swallowing, it moves downward to cover the opening of the larynx (voice box) and prevent food and drink from entering the airway. This ensures that the food and drink are directed into the esophagus and down to the stomach, rather than going into the respiratory system. The vocal cords, trachea, and alveoli are not directly involved in the process of preventing food and drink from entering the airway during swallowing.
