Quizplus · Accepted Answer

Plasma clearance refers to the volume of plasma that is completely cleared of a substance by the kidneys in one minute. This is calculated by measuring the concentration of the substance in the urine and plasma, and then using the equation: Clearance = (Urinary concentration x Urine flow rate) / Plasma concentration. Therefore, option D is the correct statement. Option A refers to filtration time, option B refers to urinary clearance, and option C refers to filtration rate.
