HEPATOBILIARY SYSTEM Flashcards
This is the largest organ inside the body
liver
What are the functions of the liver
synthesize & detoxify substancs
What 2 arteries are connected to the liver
hepatic artery and portal vein
this is where the storage & concentration of bile takes place
gallbladder
system of ducts that acts to drain bile from the liver to the duodenum
Biliary Tree
What is the correct passage way of the bile in the biliary tree?
- right and left hepatic duct
- common hepatic duct
- gallbladder
- common bile duct
what duct is between the hepatic duct and the gallbladder
cystic duct
where does the bile exit
common bile duct
what is another term for the hepatopancreatic duct
sphincter of ODDI
what is the combined duct of the hepatic & pancreatic
Ampulla of Vater or hepatopancreatic ampulla
Which hormone triggers the release of the bile to the duodenum
cholecystokenin
this is an elongated flat digestive organ
pancreas
2 functions of pancreas
endocrine and exocrine
this is concerned in the production of 3 digestive enzymes
exocrine
what are the 3 digestive enzymes produced in the exocrine
amylase, trypsin and lipase
this enzyme assist in the digestion of protein
trypsin
what is the function of amylase
assist the digestion of large molecules of starch into maltose then into glucose
what is the function of lipase
assist in breaking down lipids into fatty acids & glycerol
this are specialized cells in the endocrine function of the pancrease
islet of langerhans
what does the endocrine function do?
IL releases alpha cells (produces glucagon; increase sugar) & beta cells (insulin; decrease sugar)
Visualize the biliary tree & involves insertion of a needle into the biliary tree by puncture directly through the wall of the abdomen
PERCUTANEOUS TRANSHEPATIC CHOLANGIOGRAPHY
what kind of needle is used in percutaneous transhepatic cholangiography?
Uses a flexible, 22-gauge, skinny needle (CHIBA)
When is the percutaneous transhepatic cholangiography used?
detecting presence of calculi/tumor in the distal CBD
this is Performed by gastroenterologist
ENDOSCOPIC RETROGRADE CHOLANGIOPANCREATOGRAPHY
the ENDOSCOPIC RETROGRADE CHOLANGIOPANCREATOGRAPHY is used to?
- Visualize the biliary system & main pancreatic duct
- Provides drainage for the pancreatic enzymes into both the digestive tract & the common bile duct
What kind of instrument is used in the ENDOSCOPIC RETROGRADE CHOLANGIOPANCREATOGRAPHY
thin catheter
- Performed during surgery at the time of a cholecystectomy to detect biliary calculi
OPERATIVE CHOLANGIOGRAPHY
How much CM is injected during an operative cholangiography?
6 ml
