18. How do glomerular filtration rate (GFR) and renal clearance differ?
(A) GFR measures substances completely removed by the kidneys, while renal clearance considers filtration, reabsorption, and secretion.
(B) GFR reflects the total volume of plasma cleared by the kidneys, while renal clearance evaluates only the filtration process.
(C) GFR evaluates only the filtration process, whereas renal clearance encompasses filtration, reabsorption, and secretion.
(D) GFR and renal clearance are synonymous terms, representing the efficiency of the kidney's waste removal.
(E) GER represents the amount of urine produced, while renal clearance measures the concentration of waste in the urine.
