answered-by-expert Expert Answer

Urine is produced by the nephrons of kidneys. Urine formation takes place in 3 steps:

i) Glomerular filtration - Filtration of blood under pressure in the glomerulus. This process ia called ultrafiltration.

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.

The concentrated urine is then taken to urinary bladder through ureters and stored there, until release.
