Quizplus · Accepted Answer

The epiglottis is a flap of tissue that is located at the base of the tongue. During swallowing, it flips down over the entry to the trachea, covering it and directing food and drink into the esophagus. This helps to prevent food and drink from entering the trachea and lungs, which could cause choking or aspiration pneumonia.
