What material is urine composed of?

Urine is normally composed of water and wasted products filtered form 
the body.  The kidney produces urine.  The other main function of the 
kidney is to regulate fluid balance in the body.  It performs this 
function by using a selective osmosis system.  Basically, the way it 
works is that electrolytes (dissolved salts like sodium, potassium, 
calcium, carbonate, chloride) are pumped back into or out of urine and 
blood so that in the end, just the right amounts of electrolyte and 
water exit the kidney blood vein.  The rest ends up in urine.  
Interestingly, normal urine is sterile and has no bacteria.

Urine contains 95% water and 5% solids.  More than 1000 different 
mineral salts and compounds are estimated to be in urine.  So far, our 
scientific community knows of about 200 elements.  Some substances are:  
vitamins, amino acids, antibodies, enzymes, hormones, antigens, 
interleukins, proteins, immunoglobulins, gastric secretory depressants, 
tolergens, immunogens, uric acid, urea, proteoses, directin, H-11 (a 
growth inhibitory factor in human cancer), and urokinase.  Believe it or 
not, scientists have know for years that urine is antibacterial, 
anti-protozoal, anti-fungal, anti-viral, and anti-tuberculostatic!
