19
Q

What are the 2 clinically important sections of the peritoneal cavity related to liver?

A

Hepatorenal recess (morrisons pouch)

sub-phrenic recess

20
Q

What is the condition called and what occurs when there is a collection of puss in the 2 major recesses of the liver?

A

peritonitis-abscess formation

21
Q

What is the function of the hepatic portal vein

A

drains blood from foregut (splenic), midgut (superior mesenteric) and hindgut(inferior mesenteric drains into splenic) for first-pass metabolism and drains in to the IVC leading to right atrium

22
Q

bile drains out of gall bladder via……duct?

A

cystic

23
Q

blood supply to the gall bladder via?

A

cystic artery which is the branch of the right hepatic artery

24
Q
A
25
Q

what are the 4 ducts that make the billiary tree?

A

Common hepatic duct

right and left hepatic duct

cystic duct

26
Q

Where does the duodenum begin and end?

A

begins at pyloric sphincter and ends in gastrojejunal flexure

27
Q

What are the 2 functions of the pancreas?

A

exocrine- acinar cells-pancreatic digestive enzymes into main pancreatic duct

Endocrine-hormones-islet of Langerhans produce hormones such as insulin and glucagon and pass into blood stream

28
Q

bile duct joins with the main …..duct to form the ….of vater. both then drain in the 2nd part of the …….. this joining in the duodenum is known as the sphincter of…..

A

pancreatic

ampulla of vater

duodenum

oddi

29
Q

What are the two ways the biliary tree can be obstructed?

A
  • gall stones formation
  • carcinoma at the head of the pancreas
30
Q

What does the blockage of gall bladder lead to?

A

flow of bile back up in liver that overspills into the blood stream

31
Q

What are the blood supplies to the duodenum and the pancreas?

A

gastroduodenal artery

splenic artery

superior mesenteric artery

superior and inferior pancreatoduodenal artery

32
Q

What is the cause of pancreatitis?

A

blockage of the ampulla by a gallstone leading to bile diverted to pancreas leading to inflammation
