Liver sinusoid
Noninvasive
imaging diagnosis of sinusoidal obstruction syndrome: a pictorial review. Hepatic sinusoid blood flow diagram. Hepatic sinusoids are a complex of vascular conduits to be responsible for the exchange of blood, oxygen, and nutrients in the liver and systemic circulation. The structure of the hepatic sinusoids is composed of the sinusoidal endothelial cells and containing Kupffer cell. Under normal circumstances, the blood supply to the hepatic sinusoid blood come from the inlet flows (i.e., the hepatic artery and portal vein) and venous blood return to the heart through the outlet flows (i.e., the hepatic veins)
Liver sinusoids are a type of fenestrated/porous blood vessel which compose the 'capillary bed' of the liver parenchyma. They receive terminal branches of the oxygen-rich hepatic artery (terminal hepatic arterioles) and nutrient-rich portal vein (terminal portal venules). They facilitate vascular exchanges between the blood and hepatocytes.
