The tuft is structurally supported by intraglomerular mesangial cells . The blood is filtered across the capillary walls of this tuft through the glomerular filtration barrier, which yields its filtrate of water and soluble substances to a cup - like sac known as Bowman's capsule . The filtrate then enters the renal tubule, of the nephron . </P> <P> The glomerulus receives its blood supply from an afferent arteriole of the renal arterial circulation . Unlike most capillary beds, the glomerular capillaries exit into efferent arterioles rather than venules . The resistance of the efferent arterioles causes sufficient hydrostatic pressure within the glomerulus to provide the force for ultrafiltration . </P>

Where does blood leaving the glomerulus go next
