Pyloric antrum (antrum, lesser cul-de-sac) is the initial portion of the pyloric part of the stomach. Latin ( lingua Latīna, laˈtiːna is an Italic language, historically spoken in Latium and Ancient Rome. Gray's Anatomy the Respiratory apparatus ( Apparatus Respiratorius Respiratory system Respiratory apparatus Medical Subject Headings ( MeSH) is a huge Controlled vocabulary (or metadata system for the purpose of indexing journal articles and books Elsevier, the world's largest Publisher of Medical and Scientific literature, forms part of the Reed Elsevier group In Human anatomy, the stomach is a J-shaped hollow muscular organ of the Gastrointestinal tract involved in the second phase of Digestion, following It is near the bottom of the stomach on the left side of the pyloric sphincter, which separates the stomach and the duodenum. The pylorus (from Greek πυλωρος = "gate guard" is the region of the Stomach that connects to the Duodenum. In Anatomy of the Digestive system, the duodenum is a hollow jointed tube about 25-30 cm (10-12 in long connecting the Stomach to the Jejunum
It may temporarily become partially or completely shut off from the remainder of the stomach during digestion by peristaltic contraction of the prepyloric sphincter; it is demarcated, sometimes, from the second part of the pyloric part of the stomach (pyloric canal) by a slight groove. Digestion is the breaking down of chemicals in the body into a form that can be absorbed In the Esophagus After food is chewed into a bolus it is swallowed to move it into the esophagus The pylorus (from Greek πυλωρος = "gate guard" is the region of the Stomach that connects to the Duodenum. The pyloric canal, also known as the canalis pyloricus, is the opening between the Stomach and the Small intestine See also

Function
The pyloric antrum is the location of several important endocrine cells including Gastrin-producing G Cells (stimulate acid production) and the luminal-pH-sensitive population of somatostatin producing of D cells (responsible for shutting off acid secretion. The endocrine system is an integrated system of small organs that involve the release of extracellular signaling molecules known as Hormones The endocrine system is instrumental In humans gastrin is a Hormone that stimulates secretion of Gastric acid (HCl by the Parietal cells of the Stomach, as well as aiding in In Anatomy, the G cell is a type of cell in the stomach that secretes Gastrin. Somatostatin (also known as growth hormone inhibiting hormone ( GHIH) or somatotropin release-inhibiting factor ( SRIF) is a Peptide hormone Delta cells (δ-cells or D cells are Somatostatin producing cells They can be found in the Stomach, Intestine and the Islets of Langerhans There is a second hormone-sensitive population near the fundus. )
Etymology
