Explanation:

Carbon dioxide is a waste product of cellular respiration. It is transported by the blood to the lungs. In the lungs, it is exhaled out of the body. Maintaining fluid balance is mainly related to electrolytes and water - related mechanisms. Digestion in the stomach involves enzymes like pepsin and hydrochloric acid. Regulating blood sugar levels is the role of hormones like insulin and glucagon. Providing energy through cellular respiration is mainly the role of glucose.

To be transported in the blood and removed from the body through the lungs.
