In the liver, blood enters the hepatic sinusoids from both the portal vein and the hepatic artery. Venous blood is cleaned in the sinusoids, while arterial blood provides oxygen to the surrounding liver cells. The blood then passes from the sinusoids into the hepatic vein to return to the heart.
Unlike true capillaries, sinusoids do not have fine connective tissue surrounding them. In addition, they are larger vessels, since they are approximately 20 µm in diameter. The endothelial cells, which make up the inner surface of the vessels, are separated by hollow spaces.
