Study Notes
Blood Supply of the Stomach
- The greater curvature of the stomach is supplied by the left and right gastro-omental arteries, which form an arterial arch.
- The left gastro-omental artery is a branch of the splenic artery, and the right gastro-omental artery is a branch of the gastroduodenal artery.
- The short gastric arteries, which arise from the splenic artery, supply the fundus of the stomach.
Venous Drainage of the Stomach
- The gastric veins accompany the corresponding arteries and drain into the portal vein circulation.
- The right and left gastric veins drain directly into the portal vein.
- The short gastric veins and the left gastro-omental vein drain into the splenic vein.
- The right gastro-omental vein drains into the superior mesenteric vein.
Lymphatic Drainage of the Stomach
- The right and left gastric lymph nodes are situated along the corresponding blood vessels and drain into the coeliac nodes.
Abdominal Regions
- Nine abdominal regions are formed by two horizontal planes (transpyloric and intertubercular) and two vertical lines (right and left midclavicular lines).
- The regions are: epigastric, mesogastrial, hypogastrial, right and left hypochondriac, right and left lumbar, and umbilical.
Blood Supply of the Duodenum
- The duodenum receives blood supply from the superior and inferior pancreaticoduodenal arteries.
- The superior pancreaticoduodenal artery is a branch of the gastroduodenal artery.
- The inferior pancreaticoduodenal artery is a branch of the superior mesenteric artery.
Venous Drainage of the Duodenum
- The veins draining the duodenum are tributaries of the portal vein system, mainly through the superior mesenteric vein.
Lymphatic Drainage of the Duodenum
- The anterior lymph vessels drain superiorly to the pancreaticoduodenal lymph nodes along the splenic artery and vein.
- From the lower part of the anterior surface, lymph is returned to the pyloric lymph nodes.
- Efferent vessels pass to the celiac lymph nodes.
The Midgut (Jejunum and Ileum)
- The midgut is supported by the mesentery proper and is situated mainly in the central abdomen.
- The jejunal and ileal blood vessels, lymphatic vessels, nerves, and fatty tissue pass between the two layers of peritoneum.
Lymphatic Drainage of the Midgut
- The lymph vessels of the small intestine drain into intermediate groups of nodes arranged along the arteries in the mesentery or on the abdominal wall.
- These nodes drain to one of three groups of pre-aortic nodes arranged about the origins of the coeliac, superior and inferior mesenteric arteries.
