LIVER (slides 137,139,140 and 141)

Slide 140 (rat liver prepared with regular fixation and paraffin embedding) is quite similar to slide 139, although the hepatocytes are not quite so well preserved. Look again for central veins and portal areas and confirm your criteria for making the identification of "liver". At higher magnification notice that the cytoplasm of the parenchymal cells contains unusually large chunks of glycogen.
