Question

Quizplus · Accepted Answer

The lining of the stomach is protected by a layer of mucus, which acts as a physical barrier between the stomach acid and the wall of the stomach. This mucus layer also contains bicarbonate ions which neutralize any acid that comes into contact with it. Therefore, even though stomach acid can have a very low pH and high acidity, it does not digest through the wall of the stomach because of the protective mucus layer.
