Now, in this case, it was fully reabsorbed. So we have a renal clearance of zero, but in this case, only a slide and mouth was reabsorbed. And that means whatever the renal clearance is, it will be slightly less than 125 ML/minute, but it will be greater than 0 ML/minute. Now, one example of such a substance is urea. Urea is small enough to actually filter easily through our glomerulus, but a small percentage of it is actually reabsorbed. In fact, 60 ML/minute is reabsorbed, and that means 125 gives us about 65 ML/minute.
