Detailed explanation-1: -Urine formation occurs in three main stages in the kidney. The first is filtering things out of the blood and into the filtrate. The next is reabsorbing the important stuff from the filtrate. Finally, anything that needs to be shipped right out of the body is secreted out.

Detailed explanation-2: -Tubular secretion is the transfer of materials from peritubular capillaries to the renal tubular lumen; it is the opposite process of reabsorption.

Detailed explanation-3: -There are four basic processes in the formation of urine starting with plasma. Filtration is the mass movement of water and solutes from plasma to the renal tubule that occurs in the renal corpuscle. About 20% of the plasma volume passing through the glomerulus at any given time is filtered.
