No, worms do not have tongues. They use their muscular pharynx to push food into their digestive system.
An insect's pharynx works by contracting muscles to help push food downwards toward the esophagus. The pharynx also helps regulate the flow of air during respiration by controlling the opening and closing of the respiratory system. Insects have a tube-like structure that extends from the pharynx to the gut, allowing for both food and air to pass through.
After passing through the pharynx, the food enters the esophagus, a muscular tube that connects the pharynx to the stomach. muscle contractions push the food through the esophagus and toward the stomach.
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.
The main organ responsible for the propulsion of food through the gastrointestinal (GI) tract is the esophagus. Its function is largely mechanical, as it uses peristaltic waves of muscle contractions to push food from the mouth to the stomach.
