In clinical studies, Inulin and para-amino hippuric acid givenintraveneously until steady state is reached in a 70 kg man. Oncesteady state was reached, the following measurements werecollected: arterial plasma concentration of inulin 0.18 mg/ml, ofparaamino hippuric acid 0.21 mg/ml; renal venous plasmaconcentration of para-amino hippuric acid 0.0014 mg/ml; urine flow2.2 ml/min; urinary concentration of inulin 11.0 mg/ml, ofpara-amino hippuric acid 5.5 mg/ml. Calculate the renalvenous concentration of inulin.
Total Body Water = 42L
Extracellular Fluid = 14L
Osmolarity = 300mOsmoles/L
Intracellular Fluid = 28L
