Solution

Glomerular filtration rate (GFR):
The glomerular filtration rate is the amount of nephric filtrate formed by all nephrons of both the kidneys in 1 minute.
The glomerular filtration rate of a healthy man is 125 ml/min and a total of 180 litres of nephric filtrate is produced per day.
As the filtrate passes through the tubules, useful products like glucose, amino acids, salts, and a large amount of water are reabsorbed by the capillary network surrounding the tubule and only 1 to 1.5 litres of nephric filtrate is excreted out as urine in a healthy adult person per day.
Final answer: A healthy adult human excretes (on average) 1 to 1.5 Litre of urine per day.
