Renal plasma flow is 600 mL min⁻¹ and the filtration fraction is 20 %. A solute is present in plasma at 0.15 g L⁻¹ and 80 % of the filtered load is reabsorbed. Calculate (a) the glomerular filtration rate (GFR) and (b) the net excretion rate of the solute in mg min⁻¹.

Question

Accepted Answer

GFR = 120 mL/min; net excretion = 3.6 mg/min
