I need to ask this question from Urine Formation topic in portion Excretory Products and Elimination of Biology – Class 11

Answer 1

The correct choice is (c) 4-5 minutes

To elaborate: As we know that our kidney filters approximately 1100-1200 ml of the blood per minute and our cardiac output is 5 times this volume, therefore our kidneys take approximately 4-5 minutes to filter the whole blood of the body.
