Explanation: 

Detailed explanation-1: -The kidneys filter unwanted substances from the blood and produce urine to excrete them. There are three main steps of urine formation: glomerular filtration, reabsorption, and secretion. These processes ensure that only waste and excess water are removed from the body.

Detailed explanation-2: -Three processes are involved in urinary excretion: Filtration. Secretion. Reabsorption.

Detailed explanation-3: -Reabsorption refers to the absorption of these useful substances from the glomerular filtrate. Out of 125 litres of glomerular filtrate, only 1 litre is excreted as urine. This suggests that about 99% of filtrate is reabsorbed. The reabsorbed materials are sent back to the bloodstream.
