The Gizzard, it's the part of the worm that grinds up foods or solids.
The function of the crop in the digestive system of the the bird is to temporarily store food for later digestion. In seed eating birds the crop is like a pouch in the esophagus and no real digestion occurs there it occurs in the gizzard which grinds it all up.
Either it's beak or it's gizzard, which contains rocks and stones, designed to crush the food into smaller particles, making it easier to digest :D
Since mastication means "chewing", the teeth since it grinds up food and maybe the tongue and salivary glands which aid in the breaking down of food.
Gizzards come from the digestive system of birds, where they help grind up food for digestion.
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.
The digestive system processes food that is put into your body. The digestive system processes the food by breaking it down and absorbing the nutrients.
The crop is a muscular pouch in the digestive system of birds that stores and moistens food before digestion, while the gizzard is a muscular organ that grinds and breaks down food using grit or small stones ingested by the bird. The crop is responsible for storage and initial breakdown of food, while the gizzard's main function is mechanical digestion to further break down tough food particles.
