  1. 3 gut rotations
    • 1. gut tube rotation 90 degrees to the right
    • 2. bending to the right
    • 3. rotation arount the arterial line (SMA)
  2. Celiac Axis
    • supply foregut
    • -common hepatic
    • -left gastric
    • -splenic
  3. proper hepatic
    • up to liver
    • right gastric-back into lesser curvature, anastamose with lf. gastric
    • cystic-to gallbladder
    • L & R Hepatic-dive into liver
  4. Gastroduodenal
    • inferior
    • -supraduodenal-1st part
    • -rt. gastroepiploic-greater curvacure; major one-anastomose with L. gastroepiploic
    • -ant. & Post. Sup. Pancreaticoduodenal-in substance in pancreas
  5. Left gastric
    • anastamose with r. gastric
    • -esopogeal
    • some have accessory hepatic
  6. Splenic
    • Buried in pancreas
    • Retroperitoneal
    • go into spleen-intraperitoneal
    • Pancreatic
    • Short Gastric-upward
    • Lt. Gastroepiploic-inferior greater curvature
  7. anatamoses between celiac and superior mesenteric
    through ant. & post. sup. and ant. & post. inf. pancreaticoduodenal
  8. 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
  9. what happens if superior mesenteric artery is pulled down with adhesion
    can compress left renal vein and duodenum
  10. marginal artery feeds what?
    large intestine anatomotic loop
  11. Appendix
    • longitudinal bands of large intestine converge to appendix from cecum
    • supplied by appendicular artery
  12. small intestine vasa recta
    • straighter-jejunum
    • curvy-ilium
    • blockage-not a lot of collaterals-part becomes aschemic
  13. large intestine blockage
    collaterals-marginal branch or long branch
  14. inferior mesenteric artery
    • left colic-anastomoses with middle colic
    • sigmoid-rest (1-4) varies on number
    • superior rectal=dives into pelvis
  15. portal vein tributaries
    • superior mesenteric
    • Splenic-this and the SMV make up the portal vein
    • inferior mesenteric
    • left gastric
  16. 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
  17. portal hypertension
    • cirrhosis of liver major cause
    • elevated pressure
    • dilate vascular channels
    • engorge esophagus with blood
    • hemorage
    • can be fatal
  18. liver-venous channels
    sinusoids arteries emptying into veins to get oxygen into nutrient rich blood
  19. posterior body wall
    • unpaired visceral branches
    • paired visceral branches
    • paired parietal(body wall) branches
  20. paired visceral branches
    • suprarenal
    • -superior
    • -middle
    • -inferior
    • renal
    • gonadal
  21. paired parietal (body wall) branches
    • phrenic
    • lumbar
  22. not paired branch of posterior body wall
    median sacral
