The first 3 parts make up the proximal stomach : >Cardia: the first part, which is closest to the esophagus >Fundus: the upper part of the stomach next to the cardia >Body (corpus): the main part of the stomach, between the upper and lower parts Some cells in these parts of the stomach make acid and pepsin (a digestive enzyme), which combine to make the gastric juice that helps digest food.
