Liver sinusoid

Liver sinusoid

Sinusoid of a rat liver with fenestrated endothelial cells. Fenestrae are approx 100 nm diameter, and the sinusoidal width 5 µm.

Basic liver structure
Latin	vas sinusoideum
Code	TH H3.04.05.0.00014

A liver sinusoid is a type of sinusoidal blood vessel (with fenestrated, discontinuous endothelium) that serves 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. Kupffer cells are located inside the sinusoids and can take up and destroy foreign material such as bacteria.
