Fenestrated capillaries found
WebFenestrated capillaries are found in endocrine and exocrine glands, gallbladder, synovial membrane, ciliary body, and choroid plexus and in countercurrent flow systems as found in the renal medulla. Functionally, blood flows from an artery into arterioles that become smaller in internal diameter as they branch. WebSinusoidal capillaries are similar to fenestrated capillaries but are larger in diameter and are arranged in a looser weave to allow the presence of gaps between individual cells. These capillaries are found in tissues such as endocrine glands, which require permeability to large molecules. A Sinusoid is a special type of capillary bed, found ...
