Peripherally arranged portal tracts, each containing terminal branches of the hepatic artery and portal vein and a small tributary of the bile duct.
Which hepatocytes are most distant from the portal tract?
Hepatocytes furthest away from the portal tracts – those adjacent to the central venules – are most distant from the oxygenated arterial blood supply. These hepatocytes have little capacity for oxidative activities and contain many esterases, being involved in conjugating and detoxifying reactions.
