yes

At Low Plasma PAH concentration:

-90% (not 100%) of the true Renal Plasma Flow get cleared off PAH (PAH removed).

cz remaining 10% of the Renal Plasma Flow perfuses (goes to) the "Renal CAPSULE" ...so no opportunity to remove PAH from that plasma Flow.

hence Clearance of PAH will equal only 90% of Renal Plasma Flow said to be "Effective Renal Plasma Flow"


"D" is correct.

we can simply use the formula mentioned by maryam.

Effective RPF = RPF * Extraction rate(clearance)

RPF = Effective RPF / Extraction rate(clearance)

RPF = 585 / 0.9

RPF = 650 ml/min




*IF

Renal Extraction of PAH ................. 1.0 (assume)(100% removed)

RPF = Effective RPF / Extraction rate(clearance)

RPF = 585 / 1.0

RPF = 585 ml/min (same as the Effective RPF)
