Liver, Gallbladder, Pancreas (Ach) - W2 Flashcards
What lobe of the liver are the caudate and quadrate anatomically a part of and functionally apart of?
- Anatomically: Right lobe
- Functionally: left lobe
What 3 things are found at the porta hepatis?
- hepatic artery
- portal vein
- bile duct
often clamped to minimize blood loss following traumatic injury
Hepatic artery (proper)
- supplies liver with 20-30% of blood supply
- branch of common hepatic
- oxygenated blood
Portal vein
- collects blood from GI tract
- delivers 70-80% of blood to liver
- formed form union of
- superior mesenteric vein
- inferior mesenteric vein
- splenic vein
explain the route of bile
- L and R hepatic ducts –> form common hepatic ducts –> join the cystic duct –> forms common bile duct
- joins the pancreatic duct
- opens into major duodenal papilla
Where do gallstones commonly lodge?
- narrowest part of biliary passage - terminus of hepatopancreatic ampilla or neck of gallbladder
- blockage causes biliary colic
what makes up the cystic duct
spiral folds of smooth muscle that act to keep it open
What is removal of the gall bladder known as, and what happens after it is removed?
- cholecystectomy
- bile duct and hepatic ducts dilate to store bladder.
What does the head of the pancreas and tail touch?
- Head: found in curve of duodenum
- tail: in hilus of spleen
What does cancer of the pancreas commonly involve?
- pancreatic head
- tumors can then compress the common bile duct
What is the blood supply to the pancreas?
- Branches of splenic artery
- Gastroduodenal artery
- Superior mesenteric branches
- Anastomoses
- represent alternate route of blood flow between celiac and superior mesenteric arteries
Gastrolienal ligament
hilus of speen to greater curve of stomach
Splenorenal ligament
passes to the left kideny from the hilus - has splenic vessles
What artery supplies the gallbladder
cystic artery
