Mucus protects the lining of the stomach from acidic gastric juices.
Hydrochloric acid (HCl), lipase, and pepsin come together specifically in gastric juice. Its primary purpose is to render ingested bacteria inactive, preventing infectious pathogens from entering the intestine.
Squamous epithelium, like the skin, is found in the mucosa of the mouth and the esophagus and is thought to serve as a barrier against infection.
Gastric juice makes food particles soluble, starts digestion (especially of proteins), and transforms the contents of the stomach into a semiliquid material termed chyme, laying the groundwork for subsequent small intestine digestion.
Therefore, Mucus protects the lining of the stomach from acidic gastric juices.
