Question

Quizplus · Accepted Answer

Plasma clearance is the volume of plasma that is completely cleared of a substance by the kidneys in one minute. It is calculated as the product of urine flow rate and the concentration of the substance in urine divided by the concentration of the substance in plasma. A and B are not correct statements about plasma clearance, and C is only partially correct as it refers to the amount of a substance filtered by the glomerulus, not cleared from the plasma.
