Upper GI Tract Flashcards
parietal peritoneum
lines interior of body wall of the abdominopelvic cavity
visceral peritoneum
reflects off the wall of the abdominal cavity and suspends or encloses abdominal viscera
peritoneal cavity (abdominal cavity)
potential space between the parietal peritoneum and visceral peritoneum
greater sac
major portion of abdominal cavity
omental bursa
aka lesser sac - lies posterior to the stomach and the lesser omentum
retroperitoneum
space between the posterior parietal peritoneum and the posterior abdominal wall
ligamentum teres
separates from the falciform ligament at the inferior margin of the liver and goes to the visceral surface of the liver
falciform ligament
double layer of perietal peritoneum; extends along the interior surface of the anterior abdominal wall from the umbilicus to the inferior aspect of the diaphragmatic surface of the liver; reflects onto the diaphragm as parietal peritoneum
- @ diaphragm the leaves of the falciform ligament separate and go laterally and medially = coronary ligaments
- at extremes = triangular ligaments
***anatomical landmark dividing liver into L and R lobes (anatomic)
caudate lobe
of right lobe of liver; posterior to the hilum of liver, aka porta hepatis
quadrate lobe
of right lobe of liver; anterior to the hilum of liver, aka porta hepatis
portal triad
proper hepatic artery
portal vein
common hepatic duct
–> enter/leave hilum of liver at the porta hepatis
–> divide into primary R and L branches, subdivide further; creates the 8 “functional” segments of the liver, each fed by its own branch of the portal triad
division between L and R anatomical lobes of liver
falciform ligament (diaphragmatic surface) ligamentum teres, ligamentum venosum (visceral surface)
portal vein
about 75% of liver’s blood supply;
returning blood from intestines, spleen, pancreas and gallbladder
hepatic artery
20-30% of blood supply to liver; normal arterial blood
what are the branches of the celiac trunk
- left gastric artery (most L and superior)
- splenic artery (L, more inferior)
- common hepatic artery (R)
L gastric artery branches from the ______
celiac trunk
Left gastric artery is located/follows _________ and supplies blood to the _________
lesser curvature of the stomach, stomach
splenic artery gives rise to ________ and ________
- short gastric vessel (runs in the gastrosplenic ligament)
2. Left gastroepiploic artery (supplies portion of greater curvature of stomach and greater omentum)
splenic artery directly supplies blood to
the spleen, body and tail of pancreas
short gastric vessels run in the _______ and supply blood to the ________
gastrosplenic ligament, stomach fundus
Left gastroepiploic artery comes from the ________ and supplies the _________
splenic artery, greater curvature of stomach and greater omentum
Common hepatic artery divides into the:
- proper hepatic artery
2. gastroduodenal artery
the gastroduodenal artery comes from the ___________, gives rise to the ___________, and divides into the ________ and __________
common hepatic artery;
Right gastric artery;
Left and Right hepatic artery
gastroduotenal artery comes from the ___________ and branches into the _____________, ______________ and _______________. It runs _____________
common hepatic artery;
R gastroeiploic artery, anterior and posterior pancreaticduodenal arteries;
runs posterior to the 1st portion of the duodenum
R epiploic artery comes from the __________ and supplies the _________ and ___________
gastroduodenal artery
stomach and greater omentum
Anterior and posterior pancreaticduodenal arteries come from the ____________ and supply the ___________ and _________
gastroduodenal artery;
duodenum, head of pancreas
portal system
blood traveling through 2 capillary exchange beds before returning to the heart
portal vein
carries blood that has passed through the capillary beds in the intestinal tract, pancreas, spleen and gall bladder to the capillary bed of the liver
