Anatomy
High yield
Blood supply of the stomach
Five named arteries from the coeliac trunk form lesser and greater curvature arcades; veins drain to the portal system.
High yield
Blood supply of the duodenum
Anterior and posterior pancreaticoduodenal arcades join the gastroduodenal artery (coeliac) to the superior mesenteric artery.
High yield
The abdominal aorta
Leaves through the aortic hiatus at T12 and supplies every abdominal organ.
Celiac trunk
Supplies the stomach, liver, pancreas, spleen and the first two parts of the duodenum, at T12.
Superior mesenteric artery
The artery of the midgut, from the third part of the duodenum to the proximal transverse colon.
Inferior mesenteric artery
The artery of the hindgut. Arises at L3 and runs slightly to the left of the aorta.
External iliac artery
Continues as the femoral artery and gives off the inferior epigastric and deep circumflex iliac arteries.
Internal iliac artery
The main artery of the pelvis, its anterior and posterior divisions and their branches.
Liver blood supply and drainage
The liver’s dual blood supply: the hepatic artery brings about 25% of the flow, the portal vein the rest.
