I disagree Physiology Help!

Could someone please explain what do Renal Plasma Flow and Renal Blood flow mean? I know RPF can be measured as Clearance of PAH, but what does it mean in words?

In layman terms, plasma is the liquid component of the blood. It is devoid of the the cells that the blood contains.

Yeah okay, but why is it that RPF requires a substance that is both filtered AND actively secreted by peritubular capillaries?

Renal Plasma Flow needs a substance that is both filtered and secreted because normally blood entering Glomerulos will be 20% Filtered and 80% not filtered which will be going to the peritubular capillaries.
RPF is 600ml/min , 20% Filtered (=GFR ) , 80% not filtered ( 480 ml ) goes to peritubular capillaries.
High Plasma levels of PAH , PAH clearance = GFR
Low Plasma levels of PAH , PAH clearance = RPF.
