KNAT Practice Test Answer Explanation
The correct answer is C. Larynx. The larynx contains the voice box. It funnels air to the trachea and food past the epiglottis and down the esophagus. Just below the pharynx is the larynx, or voice box. It channels air to the trachea and pushes food past the epiglottis, which covers the trachea during swallowing to prevent food from entering the lungs. Once food passes the epiglottis, it moves toward the esophagus.
