The Liver Under the Microscope
-
Histology (also known as microscopic anatomy or microanatomy) is the branch of biology that studies the microscopic anatomy of biological tissues
-
The histology of the liver can be studied by staining sections of liver tissue and viewing them under a microscope
-
These stained samples can then be examined for drawing and labelling
-
Some example labelled diagrams of stained liver tissue are shown below
