3 gut rotations
- 1. gut tube rotation 90 degrees to the right
- 2. bending to the right
- 3. rotation arount the arterial line (SMA)
Celiac Axis
- supply foregut
- -common hepatic
- -left gastric
- -splenic
proper hepatic
- up to liver
- right gastric-back into lesser curvature, anastamose with lf. gastric
- cystic-to gallbladder
- L & R Hepatic-dive into liver
Gastroduodenal
- inferior
- -supraduodenal-1st part
- -rt. gastroepiploic-greater curvacure; major one-anastomose with L. gastroepiploic
- -ant. & Post. Sup. Pancreaticoduodenal-in substance in pancreas
Left gastric
- anastamose with r. gastric
- -esopogeal
- some have accessory hepatic
Splenic
- Buried in pancreas
- Retroperitoneal
- go into spleen-intraperitoneal
- Pancreatic
- Short Gastric-upward
- Lt. Gastroepiploic-inferior greater curvature
anatamoses between celiac and superior mesenteric

through ant. & post. sup. and ant. & post. inf. pancreaticoduodenal
Superior Mesenteric Artery
- Middle Colic-supplies Transverse colon
- Right Colic-may not have
- ileocolic-to cecum; dividing line: Lf. goes to L.I and Rt. goes to S.I.
- mesenteric
what happens if superior mesenteric artery is pulled down with adhesion

can compress left renal vein and duodenum
marginal artery feeds what?

large intestine anatomotic loop
Appendix
- longitudinal bands of large intestine converge to appendix from cecum
- supplied by appendicular artery
small intestine vasa recta
- straighter-jejunum
- curvy-ilium
- blockage-not a lot of collaterals-part becomes aschemic
large intestine blockage

collaterals-marginal branch or long branch
inferior mesenteric artery
- left colic-anastomoses with middle colic
- sigmoid-rest (1-4) varies on number
- superior rectal=dives into pelvis
portal vein tributaries
- superior mesenteric
- Splenic-this and the SMV make up the portal vein
- inferior mesenteric
- left gastric
portal vein portacaval anastomoses
- esophageal veins and rectal (hemorrhoidal) veins-outlets for blood
- para-umbilical veins and colic & splenic veins with body wall veins-minor
portal hypertension
- cirrhosis of liver major cause
- elevated pressure
- dilate vascular channels
- engorge esophagus with blood
- hemorage
- can be fatal
liver-venous channels

sinusoids arteries emptying into veins to get oxygen into nutrient rich blood
posterior body wall
- unpaired visceral branches
- paired visceral branches
- paired parietal(body wall) branches
paired visceral branches
- suprarenal
- -superior
- -middle
- -inferior
- renal
- gonadal
paired parietal (body wall) branches
- phrenic
- lumbar
not paired branch of posterior body wall

median sacral
