Pouch that helps store food after ingestion. Stomach extends from the cardia at the lower esophageal sphincter to the pylorus at the junction with the duodenum. It is J shaped and has two curvatures

bullet Greater curvature attached to greater omentum
bullet Lesser curvature  attached to lesser omentum

It has fundus, cardia, pyloric region, antrum and body

Arteries (all from the celiac trunk)

bullet

Left gastric artery from the celiac trunk

bullet

Right gastric artery from the hepatic artery

bullet

Left gastro-epiploic artery from the splenic artery

bullet

Right gastro-epiploic artery from the  gastroduodenal artery

bullet

Short gastric arteries (or vasa brevia) from the splenic artery.

Veins

bullet

Gastric veins drain into the portal vein

bullet

Prepyloric vein (of Mayo) which is a constant landmark for the position of the pylorus,  drains into the right gastric vein.

bullet

Short gastric vein drains into the splenic vein

bullet

Left gastro-epiploic vein drains into the splenic vein

bullet

Right gastro-epiploic vein drains into the superior mesenteric vein

All veins find their way into the portal vein for the splenic vein joins the superior mesenteric vein at the level of the neck of pancreas to form the portal vein.

Nerves

Parasympathetic  fibers are from

bullet

Anterior vagus nerve

bullet

Posterior vagus nerve

Sympathetic fibers are from the celiac plexus via the splanchnic nerves.
