Final answer:
The kidneys produce approximately 180 liters of filtrate per day in men and 150 liters in women, but only about 1-2 liters of urine is excreted due to reabsorption.
Step-by-step explanation:
The kidneys produce a significant amount of filtrate each day as part of their function in removing waste from the bloodstream and maintaining the body's fluid balance. The glomerular filtration rate (GFR) indicates that, on average, about 180 liters of filtrate are produced per day in males and 150 liters per day in females. Indeed, the volume of filtrate formed by both kidneys per minute (125 mL/min for men and 105 mL/min for women) leads to this daily total. However, because 99% of this filtrate is reabsorbed into the circulation, the actual volume of urine excreted is much less, at about 1-2 liters per day.
