What will happen if mucus is not secreted by the gastric glands?

AcademicBiologyNCERTClass 10

Mucus protects the stomach wall from hydrochloric acid. If the mucus is not secreted by the gastric glands then the gas will damage the inner lining of the stomach and lead to ulcers in the stomach.

[Extra information:

The stomach wall or gastric glands secretes gastric juice containing three substances hydrochloric acid, mucus, and pepsin.

One of the functions of hydrochloric acid is to kill bacteria that may enter the stomach with food.

The mucus protects the inside layer of the stomach from the damaging effect of the substance hydrochloric acid whereas the substance pepsin is an enzyme for digestion.  It helps in the digestion of proteins. 

The partially digested food then enters the small intestine for further digestion. ]
