Abdominal Aorta
The main bld. Supply to the abdomin comes from:Abdominal Aorta
Starts in aortic hiatus opposite to T12
Ends opposite to L4 by dividing into:
2 common iliac arteries
& ???

Abd. Wall branches:5 lumbar a. (each side)
1st lumbar = inf. phrenic artery

Celiac Trunk
At level of T12 just beneath the hiatus
Very short
Divides into 3 branches:
Lf.:splenic a. (largest)
Rt.:common hepatic a.
Sup.:left gastric a.
(lesser curvature superiorly)

Splenic Artery
Largest branch of celiac trunk
Pass post. to the stomach & sup. to pancreas
Enters the ?? ligament to reach the hilum of the spleen
Branches:
pancreatic arteries
short gastric arteries (to the fundus)
left gastro-epiploic a. (greater curvature on lf.)
(synonym: gastro-omental)

Hepatic Artery
Rt. Branch of celiac trunk
Pass in the Rt. Side to the hilum of the liver
Part of the portal triad (what is the triad?)

Hepatic Artery
Branches:
Rt. Gastric a.:
where??
Gastroduodenal a.:
descends behind duodenum (1st part)
gives: Rt. Gastro-epiploic & sup. Pancreaticoduodenal
2 terminations:Lf. Hepatic a.
Rt. Hepatic a.
cystic a. comes from Rt. Hepatic a.

Superior Mesenteric Artery
Arises:below celiac trunk
& just above the Lf. Renal vein
descends:
post. to neck of ??
Ant. to 3rd part of duodenum
Supplies the intestine:
from lower of duodenum
Until proximal 2/3 of
transverse colon
