1. Hepatobiliary system structure

2. Hepatobiliary System components:
Liver
Gallbladder
Bile ducts
Pancreas

3. Liver Four lobes anatomically
1) right (right lobe is the largest lobe-accounting for approximately 3/5 th-2/3rd of the liver size)
2) left
3) caudate
4) quadrate
surgeons tend to separate the lobes into 8 segments by vascularity
receives blood from an artery (hepatic artery) and also a vein (portal vein)

4. located in the upper right abdomen
largest of the visceral (internal) organs (weighs approximately 3 lbs.)
unoxygenated blood enters the liver from the portal vein and oxygenated feeds the liver through the hepatic artery
network of tubes called the biliary tree carry bile from the liver
small ducts connect to larger ducts then to a hepatic duct from the right and left lobes which unite to form the common bile duct
  connected by ligaments to the diaphragm on its upper section, and on the left, to the stomach

16. Gall bladder
pear-shaped sac, which stores the bile produced by the liver
Thin walled green muscular sac
10 cm long
tucked into the ventral fossa of the liver
stores and concentrates bile
expels bile into the cystic duct
sphincter of oddi – regulates the flow of bile back the liver
cholecystectomy – gallbladder removal (doesn’t really effect the patient to have the gall bladder removed)

22. Gallstones

23. Pancreas Three parts head, body and tail.
small organ located behind the stomach. .The bile duct travels through the pancreas immediately before it enters the small intestine. Thus any problem in the pancreas (such as cancer, pancreatitis and cysts) that is adjacent to the bile duct often causes blockage of the bile duct and jaundice.
