The food you eat is broken down by the body’s digestive system and turned into stool. After food is eaten from the mouth, it passes through the pharynx, esophagus, stomach, duodenum, jejunum, ileum, cecum, colon, rectum, and finally from the anus. After the body ingests the food, it is initially digested by the initial grinding and stirring of the teeth and the digestive juices secreted by the salivary glands in the mouth. The food passes down through the pharynx and esophagus and enters the stomach, where it is further digested under the decomposition of gastric acid and pepsin and peristaltic action of the stomach, turning it into chowder, which passes through the pylorus and enters the duodenum. In the small intestine, bile secreted from the liver, pancreatic fluid secreted from the pancreas, and intestinal fluid secreted from the intestines, etc., decompose, digest and absorb the food again. The remaining food residue enters the large intestine, where the movement of the large intestine promotes the formation of feces and pushes the fecal matter forward, which is eventually excreted in the form of feces through the anus to the outside of the body, thus completing the digestion of food.
