sinusoid
irregular tubular space for the passage of blood, taking the place of capillaries and venules in the liver, spleen, and bone marrow. The sinusoids form from branches of the portal vein in the liver and from arterioles (minute arteries) in other organs. The walls of the sinusoids are lined with phagocytic cells, called Kupffer cells, that digest old red blood cells and clear the bloodstream of toxins.
