Cardia

Sections

• 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. 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. The cardia is a very small region of the stomach that surrounds the esophageal opening.
• The fundus (from Latin 'bottom') is formed in the upper curved part.
• The body or corpus is the main, central region of the stomach.
• The pylorus (from Greek 'gatekeeper') connects the stomach to the duodenum at the pyloric sphincter. The pyloric antrum opens to the body of the stomach.
