Question

Even though glomerular filtration rate in healthy person is 180 lotre per day but the amount of urine relased per day is only ablout 1.5 litres give reason

Answer 1

This means that about 180 liters of fluid are filtered by the kidneys every day. Thus, the entire plasma volume (about 3 liters) is filtered 60 times a day! Filtration is primarily driven by hydraulic pressure (blood pressure) in the capillaries of the glomerulus.
