Question

Quizplus · Accepted Answer

The glomerular filtration rate (GFR) is the amount of filtrate that is removed from the blood per unit of time. The normal GFR is about 115-125 ml/min, which means that the kidneys filter about 70-75 liters of blood per day. The GFR is about 20% of the cardiac output, or about 20-25% of the total renal blood flow. The GFR is greater than the rate of renal reabsorption, which allows for the excretion of waste products and maintenance of fluid balance in the body.
