- The liver contains huge number of cells called hepatocytes.
-The liver is supplied with blood by two vessels, the hepatic portal vein, and the hepatic artery.
-The Hepatic vein carries blood away, while blood brought by the hepatic portal vein is deoxygenated (as it has already flowed through the walls of stomach or intestines)
- One of the main functions of the liver is regulate level of nutrients before blood flows to the rest of the body
- Inside the liver, hepatic portal vein divides into vessels called sinusoids (wider than normal capillaries with porous walls)
- Many pores between the one cell layer, but no basement membrane
- Blood flowing through the sinusoids therefore in very close contact with surrounding hepatocytes
- Hepatic artery supplies liver with oxygenated blood from the left side of the heart via the aorta
- Branches of hepatic artery join the sinusoids at various points along length, providing hepatocytes with oxygen needed for aerobic respiration
- The sinusoids drain into wider vessels that are branches of the hepatic vein
- blood from liver is carried by the hepathic vein to the right side of heart via inferior vena cava
