Blood proteins and blood cells are too large to pass through the filtration membrane and should not be found in filtrate.

Question

Quizplus · Accepted Answer

The filtration membrane is made up of three layers, including the fenestrated endothelium of the glomerular capillaries, the basement membrane, and the podocyte foot processes. These layers serve as a barrier to prevent the passage of large molecules such as blood proteins and blood cells into the filtrate. Therefore, they should not be found in the filtrate under normal circumstances.
