the mouth in the crop
The digestive system is partitioned into many regions, each with a certain function. The digestive system consists of the pharynx, the esophagus, the crop, the intestine and the gizzard. Food such as soil enters the earthworm's mouth where it is swallowed by the pharynx. Then the soil passes through the esophagus, which has calciferous glands that release calcium carbonate to rid the earthworm's body of excess calcium. After it passes through the esophagus, the food moves into the crop where it is stored and then eventually moves into the gizzard. The gizzard uses stones that the earthworm eats to grind the food completely. The food moves into the intestines as gland cells in the intestine release fluids to aid in the digestive process. The intestinal wall contains blood vessels where the digested food is absorbed and transported to the rest of the body.

A pigeon has a gizzard, crop, and cloaca that it uses to digest foods. The gizzard grinds up food and pebbles and the crop temporarily stores food. The cloaca is the opening for the intestinal, reproductive, and urinary tracts.

Stones play an important part in ostrich's digestive system. Once the ostrich swallows the stones, the go to the gizzard and they facilitate the grinding of food.
