The respiratory system provides oxygen for your cells to carry out oxidative energy-forming processes while simultaneously expelling carbon dioxide waste. The digestive system absorbs valuable nutrients (glucose, electrolytes, etc.) that participate in these reactions. The circulatory system is the plumbing that connects everything together.

Good question, but too complicated to answer in 400 characters or less. Consider taking a class or reading a book on human physiology. https://www.coursera.org/course/humanphysio.
