Liver and Biliary System Flashcards
What is the largest gland in the body
Liver
Falciform ligament divides liver into two major lobes
right lobe
left lobe
two minor lobes evident on visceral surface
caudate lobe
quadrate
is collected by ducts and carried to gallbladder for storage or passes into duodenum
Bile
two blood supplies
hepatic artery
portal vein
supplies oxygenated blood from abdominal aorta
hepatic artery
carries blood from digestive system to be filtered by liver
portal vein
primary function from imaging standpoint of the liver is :
production of bile
the biliary system main function:
- to drain waste products from the liver into the duodenum
- to help in digestion with the controlled release of bile
Biliary system consists of :
bile ducts and the gallbladder
two main hepatic ducts in the liver
right and left
right and left hepatic ducts join to form:
common hepatic duct
common hepatic duct unites with:
cystic duct to form common bile duct
route for the biliary stystem:
1.right/left hepatic ducts (comes out of liver)
2. common hepatic duct
3. cystic duct: hangs from Gallbladder
4. common bile duct
5. pancreatic duct
6. hepatopancreatic ampulla or ampulla of vater
Thin-walled musculomembranous sac usually found on visceral
surface of right lobe of liver
Gallbladder
Gallbladder functions:
Functions to store and concentrate bile
when does gallbladder evacuate bile
when activated by hormone, cholecystokinin
neck of gallbladder is consistent with:
cystic duct
produces/ regulates insulin
pancreas
as a secretion it aids in the emulsification of fats
Bile
the distal end of the common bile duct is the:
spincter of Oddi, which opens into the duodenum
unites with the pancreatic duct, which then enters the heatopancreatic ampulla or apulla of vater
common bile duct
- Percutaneous transhepatic cholangiography
- Postoperative (T-tube) cholangiography
- Endoscopic retrograde cholangiopancreatography
(ERCP)
