Normal glomerular filtration rate is - 
Select and explain. 
A. 50 ml/min, B. 125 ml/min, C. 250 ml/min, D. 500 ml/min
B: 125 ml/min
Answer: B: 125 ml/min 
Explanation: In man, resting glomerular filtration rate is about 125 ml/min (lSOL/day), the renal plasma flow is about 600 ml/min.


Thus about one-fish (20%) of plasma passing through kidney is filtered„ i.e., a fraction of renal plasma flow that is filtered (filtration fraction)
