The blank prevents food or liquids from getting into the lungs.?

The epiglottis prevents food or liquids from getting into the lungs. It is a flap of cartilage located at the base of the tongue that closes over the trachea during swallowing, directing food and liquids into the esophagus instead. This protective mechanism is essential for preventing aspiration and ensuring that the airway remains clear during the swallowing process.
