Description and Distribution
Inferior phrenic arteries.
Te inferior phrenics emerge from
the aorta at ±
12
, just inferior to the diaphragm (Figure 19.24c).
Tey serve the inferior diaphragm surface.
Celiac trunk.
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
(hĕ-pat
9
ik) gives off branches to the stom-
ach, duodenum, and pancreas. Where the
gastroduodenal artery
branches off, the common hepatic becomes the
hepatic artery
proper
, which splits into right and le² branches that serve the
liver. As the
splenic artery
(splen
9
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
(
gaster

stomach)
supplies part of the stomach and the inferior esophagus. Te
right
and
lef gastroepiploic arteries

ik)—branches
of the gastroduodenal and splenic arteries, respectively—serve the
greater curvature of the stomach. A
right gastric artery
, which
supplies the stomach’s lesser curvature, may arise from the com-
mon hepatic artery or from the hepatic artery proper.
