Document Summary

Undersurface of the liver: posterior part is superior, anterior part is inferior. Interlobar fissure: an imaginary line that runs through gallbladder and middle of hepatic vein to the ivc. About 20- 25% are arterial (hepatic arteries) 75-80% is fed venously through portal vein (bringing nutrient rich blood, has just left the gastric system) Branches off the celiac trunk (3 branches, one is common hepatic- goes straight up and goes a little to the right and becomes the proper hepatic, the proper hepatic then branches off to left/right hep arteries) 8 segments in the liver, in each segment we have a portal triad (bile duct, hepatic vein, hepatic artery), so when we take out a piece, it will still survive. Superior mesenteric, splenic (join at portal confluence and then it is the portal vein) Falciform ligament: attaches liver anteriorly to the anterior abdominal wall, divides the liver into the right/left lobes.
