LOOKING AT THE LIVER UNDER THE MICROSCOPE
Liver is made up of a lot of cylinders called Hepatic lobules.
The hepatic lobules are made up of sheets of liver cells called Hepatocytes
There is a center vein that passes through the middle of the hepatic lobules that drain
the blood from the microscopic structures and then eventually the liver itself.
The interior of the liver under the microscope- think of spreading open a book cover to
The whole represents the central vein
Each page of the book represents a sheet of the hepatocyte
In between each sheet of hepatocyte there are channels called Sinusoids.
Sinusoids are blood channels that lead away from the central vein in the hepatic
Sinusoids contain some phagocytic cells (can’t see under the microscope)
Kupffer Cells- work to clean the blood and remove any debris from the
blood in the liver
Hepatic Lobule under the microscope at the lowest power:
The white dot in the center of
the lobule is the central vein (will eventually drain into the hepatic vein)
Increasing the magnification:
The red-ish areas
are the hepatocytes.
The white lines in between the red areas are the
