Foveolar cells in the antrum of stomach. A skewed cross-section of the columns gives a false impression of being stratified epithelium. Foveolar cells line the surface of the stomach and the gastric pits. They constitute a simple columnar epithelium, as they form a single layer of cells and are taller than their width. Other mucus-secreting ...

The pylorus (/ p aɪ ˈ l ɔːr ə s / or / p ɪ ˈ l oʊ r ə s /) connects the stomach to the duodenum. The pylorus is considered as having two parts, the pyloric antrum (opening to the body of the stomach) and the pyloric canal (opening to the duodenum). The pyloric canal ends as the pyloric orifice, which

This structure consists of connective tissue covered by a simple squamous epithelium, called the mesothelium, which reduces frictional forces during digestive movements. The intraperitoneal regions include most of the stomach , first part of the duodenum , all of the small intestine , caecum and appendix , transverse colon , sigmoid colon and ...
Diagram showing parts of the stomach. The human stomach can be divided into four sections, beginning at the cardia followed by the fundus, the body and the pylorus. [7] [8] 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.
This allows the stomach to expand, therefore increasing the volume of the stomach without increasing pressure. [2] They also provide the stomach with an increased surface area for nutrient absorption during digestion. [2] Gastric folds may be seen during esophagogastroduodenoscopy or in radiological studies. [3] [4]
Gastric pits are indentations in the stomach which denote entrances to 3-5 tubular gastric glands. [1] [2] They are deeper in the pylorus than they are in the other parts of the stomach. The human stomach has several million of these pits which dot the surface of the lining epithelium.
