What will happen if mucus is not secreted by the gastric glands?
Gastric juice is produced by the gastric glands of stomach. It contains pepsinogen, HCl, and mucus. HCl imparts highly acidic pH to stomach which thus bolsters transformation of idle pepsinogen into dynamic pepsin.
Mucus protects the inner lining of stomach from the HCl produced by gastric glands. If mucus is not released it will lead to damage of the inner lining of stomach causing acidity and ulcers.
