The kidneys in humans are organs of excretion, they usually perform filtration in order to remove wastes from the blood. During filtration, water and many other substances are removed from the blood; some of these substances are re-absorbed later. Proteins and blood cells are not normally found in the kidneys' filtrate. The presence of protein in high quantity in the filtrate indicates that the cell membranes of the kidneys has been damages, therefore the proteins are able to pass through them.
