Slide 68: Liver

  2. Liver lobules

  3. Liver parenchyme

  4. Vena centralis

  5. Portal areas

Draw and annotate:

A cross-section of a liver lobule of the pig.


  1. What is the shape of the liver lobules?
  2. What types of cells are found in the lobules?
  3. How is the liver parenchyme arranged?
  4. What comprise the portal areas, and where are they found?
  5. How are the structures of each portal area distinguished from each other?
