Back 8

branch of the common hepatic artery, which is a branch of the celiac trunk.
-supplies the duodenum, some stomach.

Front 9

Back 10

brnach of abdominal aorta below celiac trunk.
3 branches:
Iliocolic artery
Right colic artery
middle colic artery

Front 11

iliocolic artery

Back 11

branch of the superior mesenteric
-supplies the ilio-cecal area of the colon.

Front 12

right colic artery

Back 12

branch of superior mesenteric
-supplies the ascending colon

Front 13

middle colic artery

supplies the transverse colon

Front 14

inferior mesenteric artery

Back 14

3rd branch of the abdominal aorta
3 branches:
-left colic artery
-sigmoidal artery
-superior rectal artery

Front 15

left colic artery

Back 15

branch of the inferior mesenteric a.
-supplies the descending colon

Front 16

sigmoidal artery

Back 16

branch of inferior mesenteric
-supplies the sigmoid colon

Front 17

superior rectal artery

Back 17

branch of inferior mesenteric
-supplies the rectum

Front 18

Renal arteries

Back 18

branches directly off of abdomin. aorta
-travel superiorly to the kidneys, at the level of the superior mesenteric branch.

Front 19

gonadal arteries

Back 19

branches of the abdominal aorta, directly below the renal branches.
Female: ovarian, run w/ suspensory ligament.
Male: testicular, run w/ spermatic cord through inguinal canal.

Front 20

lumbar arteries

Back 20

FOUR
-Branches of abdominal aorta, last ones before bifurcation (for our purposes).
-Supply the posterior abdominal wall

Front 21

Common Iliac

Back 21

Left/Right; result from bifurcation of the abdominal aorta.
Branches:
internal iliac artery
external iliac artery - femoral

Front 22

Portal vein

Back 22

Brins nutrient-enriched blood to the liver to be filtered before returning to IVC and normal circulation.
Superior/Inferior Mesenteric and Splenic veins merge to form the portal vein.

Front 23

Hepatic Portal System

Back 23

-Hepatic vein takes all filtered blood out of liver.
-Portal vein brings nutrient-rich blood from digestive organs to be filtered first before returning to IVC.

Front 24

Rectus Abdominis

Back 24

origin: symphisis pubis, sternum, costal cartilages.
insertion: symphysis pubis
-Encased in the rectus Sheath

Front 25

Rectus Sehath

Back 25

aka, abdominal fasciae;
-strong white connective tissue that encases the rectus abdominis

Front 26

External abdominal oblique

Back 26

-lateral to either side of rectus abdom.
-extends downward/inward, like putting your hand in your pants pocket.
