Answer: Mucus

Mucus is the substance that protects the stomach wall from the acidity of gastric juices. The stomach lining produces a layer of mucus that covers its inner surface, acting as a protective barrier.

The mucus layer acts as a physical barrier, preventing direct contact between the gastric juices and the stomach lining. It helps to maintain a suitable pH and protect the stomach tissues from the corrosive effects of the acidic environment.
