Liver Structure
Liver Lobule
This looped animation shows the different ways of interpreting the cellular structure of the liver lobule. |
Liver Blood Flow
Dual blood supply of the liver merges upon entry into the liver lobule at the portal field.

Hepatocytes
These are the adult functional cells forming the majority of the liver (80% of the cells).
Many different functions including:
