<prompt> Normal glomerular filtration rate is -50 mlmin125 mlmin250 mlmin500 mlmin  <response>: In man, resting glomerular filtration rate is about 125 mlmin lSOLday, the renal plasma flow is about 600 mlmin.Thus about one-fish 20 of plasma passing through kidney is filtered i.e., a fraction of renal plasma flow that is filtered filtration fraction
