Translations:Magen (Gaster)/63/en

The largest part of the stomach is formed by the gastric body (corpus gastricum). The stomach ends at the top with the fundus gastricus, which is highest in the standing patient and where the inhaled air is located (visible as a stomach bladder in the lower CT image). The fundus is at about the same level as the horizontal boundary of the liver. The esophagus ends in the pars cardiaca, which is located in the upper part of the stomach. On the outside, the stomach is covered with serous peritoneal, while the esophagus is surrounded by adventitious connective tissue.
After the corpus follows the antrum pyloricum. The transition of the porter's channel into the small intestine is formed by the m. sphincter pylori. The m. sphincter pylori is caused by the particularly strong ring muscles of the stomach. This causes the visible constriction of the canalis pyloricus.
