1) Each kidney is made up of thousands of filtration unit called nephron . nephron main work is to remove harmful substances from blood
2) in nephron filtration occur in cup shape capsule bowman s capsule associated with fine capillaries network called glomerulus . Bowman's capsule collect filter urine.
3) ultrafiltration occur in glomerulus, glomerulus reabsorb helpful substance like glucose,amino acid,salt ,water from urine.
4) the urine formed enter into a long tube called ureter through collecting duct of kidney
