What is the inner wall of the stomach made of?

The stomach is an important digestive organ. It is in the stomach that food is digested and broken down into small structures. There is the release of digestive enzymes. To prevent these enzymes from digesting the stomach itself, the inner wall of the stomach is covered with special mucus, which contains special substances that neutralize the actions of acids and do not allow them to pass to the stomach cells themselves. It is also a big misconception that if you do not eat for a long time, then digestive enzymes will begin to digest the stomach. But they are not excreted without food.
