Expert Answer:

The main component of urine is water. In addition it contains nitrogenous wastes, salts (sulphates and phosphates of sodium, potassium, calcium and magnesium), traces of pigments, drugs etc. Osmoregulation is achieved by counter  current system in man.  Amount of urine is regulated by hormones Antidiuretic hormone(secreted by posterior lobe of pituitary), Aldosterone ( secreted by adrenal cortex) and Angiotensin (secreted in juxta-glomerular apparatus of kidney)
