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 sac with an inner layer that produces enzymes, which digest proteins. Other glands produce mucus, which stops the stomach from being digested by its own enzymes. Its role is to store and digest protein.
