<prompt> What is glomerular filtration rate?100 mlmin125 mlmin150 mlmin175 mlmin  <response>: B 125 mlmin GFR in a healthy person of average size is approximately 125 mLmin. Its magnitude correlates fairly well with surface area, but values in women are 10 lower than those in men even after correction for surface area. A rate of 125 mLmin is 7.5 Lh, or 180 Ld, whereas the normal urine volume is about 1 Ld. Thus, 99 or more of the filtrate is normally reabsorbed. At the rate of 125 mLmin, in 1 day the kidneys filter an amount of fluid equal to 4 times the total body water, 15 times the ECF volume, and 60 times the plasma volume.
