Sinusoid

Endothelial cells that form sinusoids have large gaps (discontinuities) between adjacent endothelial cells as well as wide pores (fenestrations) in individual cells. These fenestrations do not have diaphragms. The basal lamina is discontinuous or absent. Shown here in the liver, these modifications allow for direct access of blood plasma to the space beneath the endothelium, into which hepatocytes project microvilli. 30,000x
