Urine is formed in three steps: filtration, re absorption, and secretion.

filtration involves the transfer of soluble components such as water and waste frm the blood into the glomerulusreabsorbtion involves the absorption of molecules, ions, and water tht are necessary for the body to maintain homeostasis from the glomerular filtrate back into the blood.Secretion involves the transfer of hydrogen ions, creatinine and drugs from the blood into the collecting duct.i thnk ther r only 3 steps
