So that means 125 ML/minute flows into the Bowman's capsule and into the tubular section of our nephron. Now, because it is fully reabsorbed, that means all that substance found within the 125 ML/minute is completely reabsorbed back into the peritubular capillaries that are found in close proximity to the tubular section of the nephron. And that means 125 ML/minute will basically be filtered back into our body. Now, what does that tell us about the renal clearance of such a substance? Well, if we take this and subtract this, we simply get zero. And that means the renal clearance of this substance is 0 ML/minute or none of that substance is actually removed from the blood plasma.
