The human stomach can be divided into four sections, beginning at the cardia followed by the fundus, the body and the pylorus.<ref name="Tortora09">{{cite book |last1=Tortora |first1=Gerard J. |last2=Derrickson |first2=Bryan H. |title=Principles of anatomy and physiology |date=2009 |publisher=Wiley |location=Hoboken, NJ |isbn=9780470233474 |pages=937–942 |edition=12., internat. student version}}</ref><ref name=Elsevier />
* The gastric '''cardia''' is where the contents of the esophagus empty from the [[gastroesophageal sphincter]] into the cardiac orifice, the opening into the gastric cardia.<ref name=SCHWARTZ2010 /><ref name=Elsevier/> A cardiac notch at the left of the cardiac orifice, marks the beginning of the [[greater curvature]] of the stomach. A horizontal line across from the cardiac notch gives the dome-shaped region called the fundus.<ref name=Elsevier /> The cardia is a very small region of the stomach that surrounds the esophageal opening.<ref name=Elsevier />
* The '''fundus''' ({{ety|la||bottom}}) is formed in the upper curved part.
* The '''body''' or '''corpus''' is the main, central region of the stomach.
* The [[pylorus]] opens to the body of the stomach. The pylorus ({{ety|el||gatekeeper}}) connects the stomach to the [[duodenum]] at the [[pyloric sphincter]].

The cardia is defined as the region following the "z-line" of the [[gastroesophageal junction]], the point at which the [[epithelium]] changes from [[stratified squamous epithelia|stratified squamous]] to [[columnar]]. Near the cardia is the lower esophageal sphincter.<ref name=SCHWARTZ2010 >{{cite book|editor-first=F.
