In flatworms, the PHARYNX is used to gather food.
The digestive system of the flatworm is made up of the mouth, the pharynx and gastrovascular cavity. The pharynx is a muscular tube through which the flat worm can suck food into its gastrovascular cavity. Food normally passes from the mouth through the pharynx and then into the intestine where the food get digested by the cells lining the intestine walls.
