Description and Distribution
Inferior phrenic arteries.
Te inferior phrenics emerge from
the aorta at ±
, just inferior to the diaphragm (Figure 19.24c).
Tey serve the inferior diaphragm surface.
Tis very large unpaired branch of the abdominal
aorta divides almost immediately into three branches: the com-
mon hepatic, splenic, and le² gastric arteries (Figure 19.24b). Te
common hepatic artery
ik) gives oﬀ branches to the stom-
ach, duodenum, and pancreas. Where the
branches oﬀ, the common hepatic becomes the
, which splits into right and le² branches that serve the
liver. As the
ik) passes deep to the stomach,
it sends branches to the pancreas and stomach and terminates in
branches to the spleen. Te
lef gastric artery
supplies part of the stomach and the inferior esophagus. Te
lef gastroepiploic arteries
of the gastroduodenal and splenic arteries, respectively—serve the
greater curvature of the stomach. A
right gastric artery
supplies the stomach’s lesser curvature, may arise from the com-
mon hepatic artery or from the hepatic artery proper.
