Abdominal Vasculature:
Arterial supply
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
& ???
Branches of Abd. Aorta
Abd. Wall branches: (Parietal)
5 lumbar a. (each side)
1st lumbar = inf. phrenic artery
Abd. Cavity branches:
(Visceral)
3 anterior
3 lateral
3 terminations
3 anterior:
celiac trunk
Sup. Mesenteric
Inf. Mesenteric
3 lateral:
suprarenal
renal
gonadal (testicular or ovarian)
3 terminations:
2 common iliacs (L4)
median sacral a.
Celiac Trunk
(G, belly)
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 (retroperitoneally)
short gastric arteries (#5-6, to the fundus)
left gastro-epiploic a. (greater curvature on lf.)
(synonym: gastro-omental)
Splenic Artery
Hepatic Artery
Rt. Branch of celiac trunk
Pass in the Rt. Side to enter the hilum of the liver
Part of the portal triad (what is the triad?)
Porta Hepatis
In the middle of visceral surface
Contains: (Portal Triad)
Portal vein (in)
Hepatic artery (in)
Bile duct (out)
Hepatic Artery
Branches:
Rt. Gastric a.:
where??
anastomose with ??
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.
Descreptive Terminology
for purposes of description the a. is divided into;
Common hepatic artery
Hepatic artery proper
Rt & Lf hepatic a.
Celiac Trunk Branches (Review)
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 ½ of duodenum

Until distal 1/3 of
transverse colon
Relations of Superior Mesenteric Artery
Sup. Mesenteric a.
Main Branches of Sup. Mesenteric
(Read Your Text)
1. Inf. pancreaticoduodenal a.
anastomose with sup. Pancreaticoduodenal a. (comes from??)
2. Jejunal & ileal branches.
3. Ileocolic a.:
to ileum, cecum & appendix, and part of ascending colon
4 branches ?
gives off the appendicular a. from (which artery?)
4. Right colic a.:
supplies the ascending colon
5. Middle colic a.:
runs forward in ?? to supply proximal 2/3 of transverse colon 
Superior Mesenteric Branches
1/2 duodenum:
Jejunum:
Ileum:
Ileocecal valve, cecum & appendix:
Ascending colon:
Proximal 2/3 of transverse colon:
Inferior Mesenteric Artery
Runs downward to the left
After it crosses lf. common iliac a,
it becomes the ??
Supplies intestine:
From distal 1/3 of transverse colon

Upper ½ of Anal canal
Runs downward to the left.
Branches of Inf. mesenteric a. (Read your text)
Lf. Colic:
supplies distal 1/3 of trans. Colon
& descending colon
Sigmoid arteries:
2-3 branches
sigmoid colon
Superior rectal a.:
continuation of inf. mes. a.
descends behind the rectum
supplies rectum &
upper ½ of anal canal
