The classic liver lobule is the traditional way to describe the organization of the liver parenchyma.
Lobules - individual lobules are seen as lighter areas with darker edges at low magnification
Lobule Structure - roughly hexagonal structure with a central vein at its center and six portal triads at its periphery. (However, the random direction of a section makes this classical description rarely seen in a single profile.)
Hepatocytes - anastomosing plates, one cell thick, radiate outward from the central vein separated by sinusoidal capillaries and supported by reticular fibers. (In this specimen, the hepatocytes contain much lipofuscin.)
