Detailed explanation-1: -Continuous fenestrated capillaries have larger openings (fenestrations) between the cells that allow the quick exchange of substances. These substances include nutrients and blood. This type of capillary is in your kidneys, small intestine and endocrine glands.
Detailed explanation-2: -The capillaries have small openings in their endothelium known as fenestrae or fenestra, which are 80 to 100 nm in diameter. Fenestra have a non-membraneous, permeable membrane, which is diaphragm-like and spanned with fibrils. This arrangement allows quick movement of macromolecules in and out of the capillary.
Detailed explanation-3: -Fenestrations are pores in the liver sinusoidal endothelium that facilitate the transfer of particulate substrates between the sinusoidal lumen and hepatocytes.
