<P> In renal physiology , ultrafiltration occurs at the barrier between the blood and the filtrate in the glomerular capsule ( Bowman 's capsule ) in the kidneys . As in nonbiological examples of ultrafiltration , pressure ( in this case blood pressure ) and concentration gradients lead to a separation through a semipermeable membrane ( provided by the podocytes ) . The Bowman 's capsule contains a dense capillary network called the glomerulus . Blood flows into these capillaries through the afferent arterioles and leaves through the efferent arterioles . </P>
