A liver sinusoid is a type of sinusoidal blood vessel (with fenestrated, discontinuous endothelium) that serve as a location for the oxygen-rich blood from the hepatic artery and the nutrient-rich blood from the portal vein.^[1]

Hepatocytes are separated from the sinusoids by the Space of Disse.

Liver sinusoids are equipped with Kupffer cells that can take up and destroy foreign material such as bacteria entering the sinusoids.
