This allows the stomach to expand, therefore increasing the volume of the stomach without increasing pressure. [2] They also provide the stomach with an increased surface area for nutrient absorption during digestion. [2] Gastric folds may be seen during esophagogastroduodenoscopy or in radiological studies.

Image of the mucosa of the stomach, showing an epithelium (at top, and also facing the elongated cavities) made up of column-shaped cells. The epithelial lining of the mucosa, differs along the gastrointestinal tract. [1]
Foveolar cells in the antrum of stomach. A skewed cross-section of the columns gives a false impression of being stratified epithelium. Foveolar cells line the surface of the stomach and the gastric pits. They constitute a simple columnar epithelium, as they form a single layer of cells and are taller than their width. Other mucus-secreting ...

The stomach is involved in the gastric phase of digestion, following the cephalic phase in which the sight and smell of food and the act of chewing are stimuli. In the stomach a chemical breakdown of food takes place by means of secreted digestive enzymes and gastric acid. The stomach is located between the esophagus and the small intestine.
