There is a small cartilage above the larynx called the “tongue of the muezzar.” When air is separated from food, This cartilage closes the trachea so that no food or water enters it. The person chokes, but when the air enters, the cartilage remains open, allowing the air to pass through the trachea and then into the lungs.
