Explanation:
Detailed explanation-1: -The excretory system gets rid of noxious and nitrogenous wastes. These nitrogenous waste products, as well as extra salt and water, are eliminated from the body by the excretory system. During cellular respiration, as cells break down carbohydrates, they release water and carbon dioxide as waste.
Detailed explanation-2: -The excretory system removes other waste from our body and keeps our blood clean. The kidneys filter the blood and reabsorb useful nutrients. In the kidneys, waste substances and water form urine. The urine goes down tubes called ureters and collects in the bladder.
