Food is sucked into an earthworms digestive tract through a mouth-like opening called the prostomium by pressure formed in its muscular pharynx. Once ingested, food travels down a long esophagus into a chamber called the crop where food is temporarily stored. After a brief storage in the crop, the food is deposited into a muscular gizzard that is constantly churning to rub and breakdown stored food. Next, the food is released into the intestines where a series of enzymes break down the food even further. Once the food can no longer be broken down, it is finally absorbed through the intestinal wall. All materials that originally entered the prostomium and could not be digested continue down the intestine and ae expelled out the anus.
