Formation and composition of urine takes place in three stages:Glomerulus filtration,Reabsorption and secretion..
1:Glomerulus filtration:The blood contains waste substances enters the glomerulus with high pressure..
2:Reabsorption: The glomerulur filtrate entering into renal tubule is silute in nature..As such the filtrate passes down the tubulr much of water gets reabsorbed..
3:Secretion:The remaining filtrate paases down the last part of the renal tubule..Here most of potassium is exchanged for reabsorbed sodium..
