Lungs eliminate waste product out from the body, in the form of ______? Answer: Carbon dioxide

Lungs eliminate the waste product, carbon dioxide, from the body in the form of gas that is exhaled. During breathing, oxygen is taken in, and the blood carries it to cells where it is exchanged for carbon dioxide, a waste product of metabolism. The bloodstream then transports this carbon dioxide back to the lungs to be expelled when you breathe out.
