--under liver: gall bladder, the storage unit for bile
--largest internal gland in the body

--cirrhosis of the liver-->can weigh up to 30 pounds
--blood supply from both the portal vein and the hepatic artery
--hepatic artery provides about 75% of the total 1500 mL/min flow, oxygen rich
--hepatic portal vein supplies recently absorbed nutrients from small intestine
--microscopic functional unit: lobule, bounded by portal triads and central veins
--hepatocytes = polygonal, next to sinusoids, in sheets that radiate from triad toward veins
--portal triad = hepatic artery branch, portal vein, bile duct

--central role in metabolism dt hepatocyte fx
--formation and excretion of bile
