gastrointestinal vessels Flashcards
main anterior midline vessels off of the abdominal aorta
celiac trunk, SMA, IMA
foregut
abdominal esophagus, liver, stomach, first half of the first part of the duodenum, gallbladder
midgut
SI after the second half of the first part of the duodenum, ascending colon, two thirds of the transverse colon
hindgut
one third transverse colon, descending colon, superior rectum
what supplies the foregut
celiac artery/trunk
what supplies the midgut
superior mesenteric artery
what supplies the hindgut
inferior mesenteric artery
three main branches of the celiac trunk
left gastric, splenic, common hepatic
the left gastric artery travels where
along the lesser curvature of the left side of the stomach
the left gastroepiploic artery travels where
along the greater curvature of the left side of the stomach
the right gastric artery travels where
along the lesser curvature of the right side of the stomach
the right gastroepiploic artery travels where
along the greater curvature of the right side of the stomach
venous drainage of the digestive tract is shunted to the liver via
the portal system of veins
the portal system of veins consists of
hepatic portal vein -> superior mesenteric vein and splenic vein -> inferior mesenteric vein
4 portosystemic anastomoses sites
esophageal, rectal, paraumbilical, retroperitoneal
