The stomach is protected by the epithelial cells, which secrete and produce a bicarbonate rich solution that coats the mucosa. Stomach protects itself from autodigestion for the continuous supply of bicarbonate stomach protect itself from whole acidic environment also. Enzymes, which make up part of the digestive juices are also secreted by the stomach wall, from gland with no barrier of mucus.
