The document summarizes the stages of digestion from the mouth through the small and large intestines. It describes how food is broken down by mechanical and chemical processes in the mouth, esophagus, stomach, and small intestines before the remaining undigested waste moves to the large intestine and is excreted as feces. Key parts of the digestive system like the tongue, pharynx, esophagus, stomach, pancreas, and intestines are identified along with their roles in breaking down food.
