useful substances from the filtrate.

Tubular secretion of unwanted substances back into the collecting ducts.

Maintaining normal blood pressure by balancing electrolytes in the blood.

FILTERATION MEMBRANEThe functional unit of the kidney is the nephron.Each kidney consists of thousands of nephron.Inside each nephron is the filtration membrane.Filtration membrane consists of;

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.

SUMMARYThe kidney play a vital role in sustaining life.
