Metabolic products are not needed by our body. Also, many of them are not toxic. For example, when organic substances are oxidized during the third stage of energy metabolism, carbon dioxide is released. The main organ of the excretory system is the kidneys. Also, the liver, lungs, and skin are responsible for the release of unnecessary and toxic substances. Carbon dioxide is excreted through the lungs. The liver is responsible for neutralizing and eliminating poisons, alkaloids, processed blood cells, and so on. Therefore, excretion is very important for the life of the organism.
