Liver: blood supply and lymph drainage
The liver receives a dual blood supply. Its arterial supply is via the left and right hepatic arteries. It also receives deoxygenated blood via the hepatic portal vein which accounts for approximately 75% of blood inflow.....
Its inflow from the portal circulation result in the liver being a prime site for metastases from the bowel.The hepatic vein and IVC increase organ stability.
Lymph from the liver can drain to the diaphragm or mediastinum but the majority of lymph drains to the hepatic lymph nodes which in turn drain into the coeliac lymph nodes and onto the thoracic duct.
This is typically the mechanism of spread of GI cancer that results in the formation of Virchow's node in the left supra clavicular fossa.
