Detailed explanation-1: -In the stomach several mucosal defence mechanisms protect the stomach against hydrochloric acid and noxious agents. The pre-epithelial protection is made up by the mucus-bicarbonate barrier. Mucus and bicarbonate, secreted by mucus cells, create a pH gradient maintaining the epithelial cell surface at near neutral pH.
Detailed explanation-2: -The stomach normally does not digest itself because of a mechanism which regulates gastric secretion. This checks the secretion of gastric juice before the content becomes sufficiently corrosive to damage the mucosa. Pure gastric juice can destroy the mucosa and produce a peptic ulcer.
Detailed explanation-3: -Your gut is lined with mucus, a slippery substance that has many functions. Gut mucus protects your gut and helps with digestion. Gut mucus may also protect you against several health conditions.
