Wall of fenestrated capillaries of the glomerulus Basement membrane Visceral layer of glomerular capsule

SAILENT FACTSApproximately (1000 -1200)ml of blood pass via the

renal artery into the kidney per minute.1.5million ml of blood pass through the kidney in each

24-hour day.The net filtration pressure (NPF) is responsible for

filtrate formation.People with kidney failure needs dialysis to filter their

blood until they can get a kidney replacement.
