LIVER
(Pig, H&E) [#82]- Each liver lobe is surrounded by a connective tissue capsule (Glisson's capsule), and each lobe is further subdivided into (classical) lobules by loose connective tissue. While in the pig each lobule is clearly demarcated by connective tissue, in the human liver, demarkation between adjacent lobules is not clear and connective tissue can be seen mainly in the sites that contain branches of the hepactic artery, hepatic portal vein and bile duct.
