explain the mechanism of urine fomation

Asked by ankitmadan | 5th Jun, 2008, 07:32: PM

Expert Answer:

Urine formation takes place in 3 steps:

i) Glomerular filtration - Filtration of blood under pressure

ii) Selective Reabsorption - Useful substances from filtrate are reabsorbed by renal tubular cells and returned to blood.

iii) Tubular secretion - Separation of unwanted substances from blood and actively secreting them into the renal filtrate.
