If [urine]PAH = 14mg/ml, urine flow = 0.9ml/min and [plasma]PAH = 0.02mg/mli) What is the clearance of PAH?ii) If the extraction ratio of PAH is 0.9, what is the renal blood flow (Hct=45%)?

• A. ClPAH = 630, renal blood flow = 1273ml/min
• B. ClPAH = 630, renal blood flow = 700mb/min
• C. ClPAH = 77, renal blood flow = 155mb/min
• D. ClPAH = 777mb/min, renal blood flow = 1569mb/min
