In brief: Not in 400 words!!!

In summary: breathing delivers oxygen to the blood.
Digestive system delivers nutrients to body to provide energy and gets rid of unabsorbed material (GUT) and toxic waste (liver). Cardiovascular or circulatory takes oxygen from lungs and nutrients from GI and delivers to the body (left circulation). Then carries "used" blood from the tissues back to the lungs to be oxygenated again (right circ).
