Fig. 53◊The arterial supply of the stomach.

Fig. 54◊The lymph drainage of the stomach.
•◊◊Area I drains along the right and left gastric vessels to the aortic nodes.
•◊◊Area II drains to the subpyloric and thence aortic nodes via lymphatics along the
right gastro-epiploic vessels.
•◊◊Area III drains via lymphatics along the splenic vessels to the suprapancreatic
nodes and thence to aortic nodes.

•◊◊the right gastro-epiploic artery—from the gastroduodenal branch of the
hepatic artery;
•◊◊the left gastro-epiploic artery—from the splenic artery;
•◊◊the short gastric arteries—from the splenic artery.
The corresponding veins drain into the portal system.
The lymphatic drainage of the stomach accompanies its blood vessels.
The stomach can be divided into three drainage zones (Fig. 54).
•◊◊Area I—the superior two-thirds of the stomach drain along the left and
right gastric vessels to the aortic nodes.
•◊◊Area II—the right two-thirds of the inferior one-third of the stomach
