Is it true that the stomach lining resists its own acid because of a protective mucus layer and bicarbonate secretion?
Yes. Reference sources state the stomach's gastric mucosal barrier consists of a mucus layer that traps bicarbonate-rich fluid, which neutralizes acid diffusing toward the epithelium, and that gastric glands secrete protective mucus and bicarbonate. A study of H. pylori and a pathophysiology text likewise describe the mucus coating as the barrier that keeps acid from the sensitive lining.
