The three main steps of urine formation are1) Glomerular filteration, 2) Reabsrption, 3) Secretion

Glomerular filteration occurs in malphgian corpuscle formed together by glomerular and its surrounding Bhowman's capsule.Reabsoption and secretion occurs in highly coiled renal tubule.

Filtration involves the transfer of soluble components, such as water and waste, from the blood into the glomerulus.Reabsorption involves the absorption of molecules, ions, and water that are necessary for the body to maintain homeostasis from the glomerular filtrate back into the blood.Secretion involves the transfer of hydrogen ions, creatinine, drugs, and urea from the blood into the collecting duct, and is primarily made of water.Blood and glucose are not normally found in urine.Key Termsurine: A liquid excrement consisting of water, salts, and urea, which is made in the kidneys then released through the urethra.glomerulus: A small, intertwined group of capillaries within nephrons of the kidney that filter the blood to make urine.

The kidneys filter unwanted substances from the blood and produceurineto excrete them. There are three main steps ofurine formation: glomerular filtration, reabsorption, and secretion. Theseprocessesensure that only waste and excess water are removed from the body.
