<prompt> Normal GFR is ?125 mlmin90 mlmin60 mlmin150 mlmin  <response>: Ans. is a i.e., 125 mlmin In man, resting glomerular filtration rate is about 125 mlmin 180Lday, the renal plasma flow being about 600 mlmin. Thus about one-fifth 20 of plasma passing through kidney is filtered, i.e., fraction of renal plasma flow that is filtered filtration fraction is 0-2.
