gallbladder
important in the storage and concentration of bile
bile
important for the normal absorption of fats from the small intestine
pancreas
excretes digestive enzymes into the 2nd last of the duodenum
necessary for the digestion of food
liver
largest organ in the body
receives nutrients absorbed from GI tract
functions-
glycogen storage, bile secretion, other metabolic functions
liver - surface anatomy
protected by ribs 7-11
location changes in breathing
INFERIOR to right semi-diaphragm POSTERIOR AND INFERIOR - gallbladder INFERIOR - hepatic flexure POSTERIOR - right kidney, right adrenal gland, IVC, abdominal aorta POSTERIOR AT LEFT SIDE - stomach
liver - anatomy
4 anatomical lobes right lobes quadrate lobe caudate lobe left lobe
8 functional loves
related to vasculature and bile drainage
porta hepatis
site of entrance for portal triad structures
liver - functional anatomy
8 functional segments hepatic artery hepatic portal vein bile drainage venous drainage
IVC and hepatic veins
lack valves
increase in central venous pressure is directed to the liver
portal triad
contains main structures that enter or leave the liver parenchyma
run within the hepatoduodenal ligament
coeliac trunk
first of three sideline branches of the aorta
retroperitoneal
leaves aorta at T12
supplies the organs of the foregut
3 branches:
splenic artery
left gastric Sartre
common hepatic artery
spleen
splenic artery has a very tortuous course
