4.1 HUMAN URINARY SYSTEM
The products of metabolism which are not needed by the organism are called waste products. These are harmful if allowed to accumulate in the body. They must be either removed or deposited as harmless insoluble form. The waste products include urea, uric acid; toxic substances such as pesticides, drugs, food additives.

The science concerned with structure, functions and diseases of the kidneys is called nephrology.
Carbon dioxide and water vapour produced during respiration are also metabolic wastes. The process by which metabolic waste products and toxic materials are removed from the body of an organism is called excretion.
