The stomach's main function is digestion. It does this by: The stomach uses pepsin (enzyme) and peptidase (another enzyme) to break down proteins in your food. The acid released by the stomach doesn't break down food it only provides a good environment for the enzymes to work in.
The stomach is a muscular, hollow, dilated part of the digestive system which functions as an important organ of the digestive tract in many animals, including vertebrates, echinoderms, insects (mid-gut), and molluscs.he stomach lies between the esophagus and the duodenum (the first part of the small intestine). It is in the left upper part of the abdominal cavity. The top of the stomach lies against the diaphragm. Lying behind the stomach is the pancreas.
