Answer
Living creatures excrete themselves. It is necessary to eliminate certain waste and toxic products, such as carbon dioxide, urea etc. When these toxic materials are not removed from the body, they get mixed with blood and can cause poisoning that slows down critical chemical reactions and damage the cells of the body. Hence it is necessary to remove such poisonous waste materials from our body.
