Form a piece of the throat. Usually the throat is open and the air flow is smooth. When swallowing, the throat is closed so that the food ball can enter the pharynx.

The leaf flap of cartilage at the back of the tongue root can prevent food and liquid from entering the trachea when swallowing. When swallowing food, epiglottis descends and covers the larynx (the top of trachea), and the larynx simultaneously produces upward reflex movement, thus effectively closing the tracheal inlet.
