The system of functions works in the body by giving the body the various nutrients that it needs to function with all
other systems, not just the digestive. See, the digestive system gives the body food which stores nutrients and vitamins that
the body requires to function. It gives the energy and power to other organs not necessarily used in the digestive
system, but required for daily use. This is how it functions with the body, by aiding it and making sure it can do what it
wants to do by providing energy.
