The wall of the stomach is structurally similar to other parts of the digestive tube, with the exception that the stomach has an extra oblique layer of smooth muscle inside the circular layer, which aids in performance of complex grinding motions.
The inner wall of the stomach is a smooth wall that is used to keep in the hydrochloric acid produced by the stomach. It is called the mucosal lining.
Muscles in the stomach wall contract and relax, helping churn the food with digestive juices, speeding up the digestion of food.
A hole in the stomach wall is known commonly as an ulcer. Ulcers are caused by an overabundance of hydrochloric acid within the stomach. The acid weakens the stomach lining and penetrates the stomach wall, causing ulcers.
The stomach has to digest the food. The wall of the esophagus has to pass the food to stomach. So the walls of both are designed by nature like that.
