Figure 19.24
Arteries of the abdomen.
Te arterial supply to the abdominal organs arises from the
abdominal aorta
(Figure 19.24a)
. Under resting conditions,
about half of the entire arterial flow moves through these
vessels. Except for the celiac trunk, the superior and inferior
mesenteric arteries, and the median sacral artery, all are paired
vessels. Tese arteries supply the abdominal wall, diaphragm,
and visceral organs of the abdominopelvic cavity. We discuss
the branches in the order of their issue.
