What does the pharyngeal Muscle do in a worm?

In worms, the pharyngeal muscle plays a crucial role in the feeding process. It helps to pump food into the digestive tract by contracting and relaxing, creating a suction effect that draws in organic matter and microorganisms from the environment. This muscular action facilitates the worm's ability to ingest and process nutrients efficiently. Additionally, the pharyngeal muscle aids in the movement of food through the esophagus to the crop and gizzard for further digestion.
