Sinusoid capillaries exhibit large openings in the endothelial cells as well as a discontinuous basement membrane; this allows for much greater movement of fluid and cells into and out of the capillaries.

Detailed explanation-2: -Sinusoids are fenestrated discontinuous capillaries found in the liver, spleen, and bone marrow.
