Main Components of the Excretory System
There are various kinds of poisons hidden throughout our body which need to be identified and eliminated in order to help the body function properly. The process of excretion involves finding and removing waste materials produced by the body.
The process of excretion involves the removal of the metabolic wastes of an organism. Wastes that are removed include carbon dioxide, water, salt, urea and uric acid.
Several organs are involved with the excretory system, including the kidneys, sweat glands, lungs and rectum. The primary organs of excretions, however, are the kidney.
Main Organs of the Excretory System & their functions:
- Lungs - removal of excess carbon dioxide
- Liver - produces urea and uric acid as a by-product of the breakdown of proteins
- Skin - removal of excess water, salt, urea and uric acid
- Urinary System - kidneys filter the blood to form urine, which is excess water, salt, urea and uric acid
