Digestive System

When food is consumed by segmented worms, the food will first enter the mouth of the worms. The food will then pass through a muscular structure called pharynx; the structure used to such food into gastrovascular cavity. After, the esophagus expands into a thin-walled structure, the crop. Just posterior to the crop is the gizzard, which is a grinding sturcture with thick, muscular wall, and this also where the most of the digestion takes place. When food passes though the intestine, where further digestion and absorption of the nutrients occurs. The enzyme that produced in the intestine helps to break down food into small particles. Finally, the intestine ends at the anus, where the wastes exit.
