Anatomical terminology

The gastric folds (or gastric rugae) may be seen during esophagogastroduodenoscopy or in radiological studies. They provide the stomach with increased surface area for nutrient absorption.[citation needed] When food enters the stomach, these folds fold inward and become stretched in. The purpose is to allow it to expand. This therefore allows expansion in volume of the stomach without increased pressure.
