sinusoid

 [si´nŭ-soid]
1. resembling a sinus.
2. a form of terminal blood channel consisting of a large, irregular, anastomosing vessel, having a lining of reticuloendothelium but little or no adventitia. Sinusoids are found in the liver, adrenal glands, heart, parathyroid glands, carotid bodies, spleen, hemolymph glands, and pancreas.

si·nu·soid

(si'nŭ-soyd),
1. Resembling a sinus.
2. Sinusoidal capillary; a thin-walled terminal blood vessel having an irregular and larger caliber than an ordinary capillary; its endothelial cells have large gaps and the basal lamina is either discontinuous or absent.
