The body has an interesting way of using deriving uses fromwaste material prior to its disposal. For example, carbon dioxideis a waste product of cellular respiration, and is disposed ofthrough the lungs. However, prior to its removal, it is the sourceof one of the most important buffer systems in the body—thecarbonic acid/bicarbonate buffer system. Identify and describe twoother waste products in the body that have a critical role in bodyfunction. And no, removal of toxins from the body—or any relatedfunction—does not count; the waste product in question (or what itcan turn into) must have some actual positive effect on the bodyprior to its disposal.
