Side, Large stomach or abdomen (rice bag) is part of the digestive tract that blooms, located inside the abdomen slightly to the left or below diagframa, in front pancreas, while nodes attached to the left fundus. The shape, size and position depend on the shape of the body, attitude, and the degree of stretching of the stomach. Normal gastric capacity is 1-2 liters .

Side, Fundus , corpus, and pyloric stomach anatomy is three. Fundus is an enlarged section to the left and above the entrance of the esophagus into the stomach. The corpus is the central part, and the pyloric antrum is the lower part. Gastric pyloric sphincter ends with. There are two lesser curvature of the concave-shaped bottom and left boundary is the major curvature.

Both ends of the hull is protected by a sphincter that regulates the income and expenditure. Cardia sphincter or sphincter or the lower esophageal sphincter prevents backflow of substances to the preformance of the esophagus. In the area known as the pars gastric cardia. Pyloric sphincter to protect the hole between the pars pilorika stomach and first part of the intestine into the stomach. Pyloric sphincter attract attention in the clinic due to narrowing (stenosis) can occur as a complication of peptic ulcer disease. Spasm of the muscle fibers it prevents duodenal food to perfection, so that the baby vomit.

Gastric mucous layer is composed of folds called rugae longotudinal temporary, allowing the stretch. Some types of glands located in this layer are grouped according to the anatomy of the stomach where they are located. Cardia cardia glands located hole and secrete mucus. Fungdus glands and gastric glands are located in the fundus and most of the gastric corpus. Fundus gland has three major cell types, cells or cells that secrete zimogenik pepsinogen, which is converted to pepsin in an acidic environment. Parietal cells which secrete hydrochloric acid and water. Neck cells are found in the neck glands and produce gastrin. Other substances secreted in the stomach are enzymes of various electrolytes, especially sodium, potassium, and chloride. Intristik factor secreted by parietal cells. Factors intristik joined with vitamin B12, vitamin B12 is absorbed allowing the intestine, resulting in shortages intristik pernicious anemia factor.

Stomach get completely nerve supply and the autonomic nervous system. The entire blood supply of the stomach and pancreas (and liver, gallbladder, and spleen), mainly originating from the celiac artery trunk seliakus atu, which ramify branches that supply the minor and major curvature. Two branches of arteries that are important in the clinic is gastoroduodenalis and parkretikoduodenalis, which runs along the bulbos puterior duodenum. Venous blood from the stomach and duodenum, as well as originating from the pancreas, spleen and other parts of the intestine, goes to the liver via the portal vein.
