Which two human body systems are involved in bringing glucose into the body and then taking it to the individual cells to serve as a reactant in the process of cellular respiration?

The glucose and the oxygen travel out into the body through the circulatory system to reach cells that need energy. The cells use the glucose and oxygen from the circulatory system for energy production.
