The movement of the walls of the stomach is accomplished by a group of smooth muscle that undergoes what is called peristaltic action.
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.
It is called Peristalsis.
The wall of the stomach contains blood vessels, nerves, connective tissue, and muscle layers. These components work together to regulate digestion and movement of food through the stomach.
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 wall of the stomach is thicker and has an additional layer of smooth muscle called the muscularis externa, which allows for mixing and churning of food. The stomach also secretes digestive enzymes and acid to help break down food. In contrast, the wall of the esophagus is thinner and lacks the specialized functions of the stomach, mainly designed for transportation of food to the stomach.
The stomach walls contract and relax in a process called peristalsis to help mix and break down food. This movement helps propel food to the small intestine for further digestion and absorption of nutrients.
If it isn't caused by an injury, it's called an ulcer.
