Mucus prevent inner lining of stomach from HCL. Mucus prevents drying of inner lining of the stomach. Mucus helps in easy movement of food particles through digestive system. If mucus is not secreted food will not easily moved through digestive system. HCL will damage the stomach lining and the digestion process will not take place.
