visceral and parietal
what is between the visceral and parietal layers of the gut? what fills the cavity?
peritoneal cavity…filled with serous fluid
is the parietal layer sensed by visceral of general sensory fibers? what about the visceral layer?
general sensory for parietal and visceral for visceral

supracolic
infracolic
name the three recesses of the greater sac of the gut
subphrenic
subhepatic
paracolic (gutters)
where is the lesser sac found in the gut?
under the lesser omentum…so behind stomach and liver
name the three recesses of the lesser sac
superior
inferior
splenic
what is the name of the opening between the lesser and greater sac of the gut?
omental foramen
name the four boundaries of the omental foramen
caudate lobe of liver
first part of duodenum
hepatoduodenal ligament
inferior vena cava
what vein is a boundary for the omental foramen?
IVC
what portion of the liver is a boundary for the omental foramen?
caudate lobe
what part of the small intestine is a boundary for the omental foramen?
duodenum
what three important structures are in the hepatoduodenal ligament?
common bile duct
portal vein
proper hepatic artery
what are mesenteries?
double layers of peritoneum that reflect off body wall and help suspend bodily organs
what often travels in mesenteries to organs?
blood supply
what is the root of a mesentery?
where the parietal layer reflects against the posterior body wall and leads to the start of a mesentery
what is an peritoneal ligament made of?
double layers of peritoneum that link organs together
what does the ligamentum teres hepatis link?
liver to liver
what does the gastrolienal ligament link?
stomach and spleen
what does the lienorenal ligament link?
spleen and kidney
name the three arteries that supply the gut?
celiac trunk
superior mesenteric
inferior mesenteric
name the three branches of the celiac trunk
common hepatic
splenic
left gastric
what doe the celiac trunk arise from?
the aorta
the celiac trunk supplies the foregut which includes what 6 structures
esophagus stomach pancreas part of duodenum liver spleen
the hepatic artery branches into three arteries…name them
proper hepatic
right gastric
gastroduodenal
name the two branches of the splenic artery
short gastric
left gastroepiploic
what does the left gastric artery feed?
the lesser curvature of the stomach
what artery feeds the greater curvature of the stomach?
the splenic artery
what does the superior mesenteric artery arise from?
aorta around the level of the pancreas
what 6 structures does the superior mesenteric artery provide blood supply to?
jejunum ileum cecum appendix ascending colon part of transverse colon
name the six branches of the superior mesenteric artery
right colic middle colic ileocolic jejunal and ileal branches appendicular inf. pancreaticoduodenal
name four things the inferior mesenteric provides blood to
transverse colon
descending colon
sigmoid colon
proximal rectum
what vessel from the superior mesenteric and anastamose and help out the transverse colon more with blood?
middle colic branch…AKA artery of Drummond
what is the artery of drummond? what can it do?
middle colic artery…can anastamose and help the transverse colon if it is not getting enough supply from the left colic
name the three branches of the inferior mesenteric artery
left colic
sigmoud
superior rectal
what is the hepatic portal system?
veins from gut meet and form hepatic vein that goes through the liver to be filtered before entering circulation again
what three veins form the portal vein of the hepatic system?
splenic vein
superior mesenteric vein
inferior mesenteric vein
if you have an obstruction in the liver flow of blood…what can happen?
blood can be re-routed around the liver
where can the left gastric vein be routed if liver has back up?
esophageal veins and into azygos veins
where can the paraumbilical veins be re routed if liver is backed up?
superficial veins on abdominal wall
where can the superior rectal veins be re routed if liver is backed up?
middle and inferior rectal veins1
if you have liver cirrhosis and blood is routed around the liver…what are you at risk for?
hemorrhoids
what is the clinical sign of rectum anastomosis?
anorectal varices (varicose veins)
what is the clinical sign of umbilicus anastomosis?
caput (superficial systemic blood flow) varices
what is the clinical sign of esophagus anastomosis?
esophageal varices
