Final answer:
On average, a human produces about 0.9 to 1 mL of urine per minute, which amounts to around 1 to 2 liters per day. Daily urine production is calculated by multiplying the per-minute amount by the number of minutes in a day, yielding an average of around 1296 mL/day. This volume can range from 600 mL to 2500 mL depending on individual factors.
Step-by-step explanation:
Normally, the amount of urine produced by the human body every minute can vary. However, when considering the Glomerular Filtration Rate (GFR), which measures the volume of filtrate formed by both kidneys per minute, it is clear that not all filtrate becomes urine. In fact, out of the approximately 120 to 125 mL/min of filtrate produced in males and 105 mL/min in females, the vast majority is reabsorbed back into the bloodstream. Consequently, only about 0.9 to 1 mL of urine is produced every minute, which translates to approximately 1 to 2 liters of urine over the course of a day.
To calculate daily urine production, one would multiply the urine production per minute by 60 minutes and then by 24 hours, which demonstrates that an average adult produces roughly 1296 mL (around 1.3 liters) of urine per day, though this can range from 600 mL to 2500 mL based on various factors including hydration levels and health status.
