Why Doesn't The Stomach Digest Itself?

The lining of the digestive tract prevents acid from burning through the tissue of your stomach... The contents of the stomach are acidic enough to dissolve a razor blade.
To prevent the stomach "wall" from from being digested, it is protected by a layer of alkaline mucus.
The cells of stomach lining are replaced at a rate of half a million each minute,
so that the stomach effectively has a new layer every 3 days!

Good Luck!

It tries not to. The stomach lining is a mucous membrane that secretes mucous fluid. The mucous fluid affords some protection but the mucous membrane is continually renewed.
