Answer:
Filtration.
Explanation:
Urine formation occurs in three steps: filtration, reabsorption, and secretion. Filtration involves the transfer of water, and waste (soluble components) from the blood into the glomerulus, and glomerular is defined as the small group of intertwined capillaries within nephrons of the kidney which helps to filter the blood to make urine.
During the filtration process, blood enters the arteriole than flow into the glomerulus where water, and nitrogenous waste (filterable blood components), will move inside of the glomerulus, and cells, and serum albumins (non-filterable components) will exit from the arteriole. To form the glomerular filtrate, filterable components accumulated in the glomerulus.
