Anatomy of Jaundice Flashcards
what is jaundice?
increased bilirubin in the blood, causing yellow skin and eyes
what is bilirubin?
a normal by product of the breakdown of red blood cells
where does the breakdown of red blood cells occur?
spleen
liver
what is bilirubin used to make and where?
bile in the liver
what is the role of the gallbladder involving bile?
stores and concentrates bile
what does the pancreas excrete into the second part of the duodenum?
digestive enzymes
where is the portal triad found?
the free edge of the lesser omentum
what vessels are found in the portal triad?
hepatic artery
hepatic portal vein
common bile duct
what is the first of the three midline branches of the abdominal aorta?
the celiac trunk
where is the celiac trunk found in relation to the peritoneum?
retroperitoneal
where does the celiac trunk arise?
around the level of T12
what organs does the celiac trunk supply?
the organs of the foregut
what are the three branches of the celiac trunk and what do they supply?
splenic artery - spleen
hepatic artery - liver
left gastric artery - stomach
what artery does the gastroduodenal artery branch off of?
hepatic
where does the splenic artery travel?
along the superior border of the pancreas
where is the spleen found in relation to the peritoneum?
inntraperitoneal
what protects the spleen?
ribs 9-11
what are the two flexures of the colon and what sides are they on?
splenic flexure - left
hepatic flexure - right
what four vessels form the blood supply to the stomach?
right and left gastric
right and left gastro omental
pairs anastamose together
what arteries run along the lesser curvature of the stomach?
gastric arteries
what arteries run along the greater curvature of the stomach?
gastro omental arteries
where does the blood supply to the liver come from?
the hepatic artery
the hepatic portal vein
where does the liver lie?
the right upper quadrant
what protects the liver?
ribs 7-11
how can the liver be split up?
four anatomical segments
eight functional segments
what are the four anatomical segments of the liver?
right lobe
left lobe
caudate lobe
quadrate lobe
what divides the right and left lobes of the liver?
the falciform ligament
what lobes of the liver are found on the posterior surface?
caudate
quadrate
what vessels are involved in venous drainage of the liver?
via three main hepatic veins into the IVC
caudate lobe has its own hepatic veins which drain into the IVC
what organs are drained via the hepatic portal vein?
all - fore, mid and hind
where does the splenic vein drain?
organs of the foregut
to the hepatic portal vein
where does the inferior mesenteric vein drain?
hindgut
to the splenic vein
where does the superior mesenteric vein drain?
midgut organs
to the hepatic portal vein
what is the role of the gallbladder?
stores and concentrates bile in between meals
how does bile flow in and out of the gallbladder?
via the cystic duct
what makes up the blood supply to the gallbladder?
the cystic artery
a branch of the right hepatic artery
