Ammonia is extremely toxic to the body and must be converted into less toxic waste products such as urea before it can be excreted by the kidneys. Urea is the primary waste product excreted by the kidneys and is derived from ammonia. Carbon dioxide is a waste product produced by cellular respiration and is not toxic to the body. Oxygen is not a waste product but rather a necessary molecule for cellular respiration. Electrolytes are important ions that are regulated by the kidneys, but they are not waste products.
