The gastroesophageal junction (also known as the esophagogastric junction) is the junction between the esophagus and the stomach, at the lower end of the esophagus. [13] The pink color of the esophageal mucosa contrasts to the deeper red of the gastric mucosa, [ 6 ] [ 14 ] and the mucosal transition can be seen as an irregular zig-zag line ...
The angle of His, also known as the esophagogastric angle, is the acute angle created between the cardia at the entrance to the stomach, and the esophagus.It helps to prevent acid reflux of stomach acid into the esophagus.
Near the gastroesophageal junction lie cardiac glands, which primarily secrete mucus. [22] They are fewer in number than the other gastric glands and are more shallowly positioned in the mucosa. There are two kinds - either simple tubular glands with short ducts or compound racemose resembling the duodenal Brunner's glands.
The lower esophageal sphincter is a muscular sphincter surrounding the lower part of the esophagus. The gastroesophageal junction between the esophagus and the stomach is controlled by the lower esophageal sphincter, which remains constricted at all times other than during swallowing and vomiting to prevent the contents of the stomach from ...

The ring is usually located a few centimetres above the gastro-esophageal junction, where the esophagus joins the stomach. Schatzki rings can often resemble a related entity called an esophageal web. Esophageal webs also contain extra mucosal tissue, but do not completely encircle the esophagus. [citation needed]
For example, gastroesophageal reflux disease (GERD) with reflux esophagitis is treated with proton pump inhibitors. Esophageal rings or strictures may be treated with esophageal dilation. Simple observation may be considered, [5] especially if symptoms are minimal or absent. If symptoms are severe or persistent, peroral endoscopic myotomy (POEM ...
The gastrointestinal tract (GI tract, digestive tract, alimentary canal) is the tract or passageway of the digestive system that leads from the mouth to the anus.The GI tract contains all the major organs of the digestive system, in humans and other animals, including the esophagus, stomach, and intestines.
