Accepted Answer

Continuous capillaries have a complete lining of endothelial cells, which creates a continuous barrier between the blood and surrounding tissues. Fenestrated capillaries have small pores or fenestrations in the lining, while sinusoidal capillaries have larger gaps between cells and are found in certain organs such as the liver and spleen. Sinusoids and vasa vasorum are also specialized types of capillaries.
