The pharynx carries both food and air. It is a passageway at the back of the oral and nasal cavities that leads to the esophagus (for food) and the trachea (for air).
A number of things are involved in moving food into the pharynx so goes down into the esophagus. The tube is lubricated with mucus, the tongue helps push the food further and the smooth muscle lining the tract also pushes the food down.

Food enters the mouth. The pharynx acts as a suction pump; its muscular walls draw in food. In the pharynx, the pharyngeal glands secrete mucus.
Food such as soil enters the earthworm's mouth where it is swallowed by the pharynx.
