Which part of the respiratory system is correctly paired with its function?

The epiglottis is a flap of tissue that covers the opening to the larynx when you swallow, helping keep food out of the airway. Alveoli exchange gases and do not contract to move air; the voice box is the larynx, not the structure that warms incoming air; and goblet cells make mucus, not white blood cells. Therefore, “The epiglottis prevents food from entering the larynx” is correct.
