The epiglottis is a flap of cartilage located at the base of the tongue that serves a crucial role in the respiratory and digestive systems. During swallowing, it closes off the trachea to prevent food and liquids from entering the airways, directing them instead into the esophagus. This protective mechanism helps prevent choking and aspiration, ensuring that air flows freely into the lungs while allowing safe passage for food.
