<P> The glomerulus is a tuft of small blood vessels called capillaries located within Bowman 's capsule within the kidney . Glomerular mesangial cells structurally support the tufts . Blood enters the capillaries of the glomerulus by a single arteriole called an afferent arteriole and leaves by an efferent arteriole . The capillaries consist of a tube lined by endothelial cells with a central lumen . The walls have a unique structure : there are pores between the cells that allow water and soluble substances to exit , and after passing through the glomerular basement membrane , and between podocyte foot processes , enter the capsule as ultrafiltrate . </P>
