• A. 125 mL; 180 L; 1.5 L
• B. 100 mL; 150 L; 1.8 L
• C. 135 mL; 180 L; 1.8 L
• D. 140 mL; 150 L; 1.8 L

Answer 1

The correct option is A 125 mL; 180 L; 1.5 L

GFR is the amount of filtrate formed per minute by the glomerulus of the nephrons in the kidneys. In a healthy person the GFR is about 125 ml/min which makes it 7.5 liters per hour and 180 liters per day. Of the 180 liters of filtrate formed per day only 1.5 liters is passed through the urethra as urine, rest of it is reabsorbed by the the tubules of nephron. Thus, the correct option is A.
