Your kidneys play a vital role in keeping your blood composition constant. They filter your blood to remove excess water and waste products, which are secreted from your kidneys as urine. One quarter of your blood supply passes through your kidneys every minute. It enters your kidney and is distributed to minute filtration units known as nephrons.
The average human has about 1.0 to 1.5 gallons of blood. The kidneys continually filter this throughout the day, all the blood being filtered about once every 45 minutes or so. The BBC Body page puts the figure at 150 liters a day which is around 40 US (33 UK) gallons. Other data source puts the figure at about 180 liters a day, which is 48 US ( 40 UK) gallons.
