The structure that prevents choking is the epiglottis, a flap of cartilage located at the root of the tongue. It functions as a valve that closes over the trachea during swallowing, directing food and liquids into the esophagus instead. This mechanism helps ensure that air enters the lungs while food is directed to the digestive tract, reducing the risk of choking.
