Explanation:
The heart, blood and blood vessels work together to service the cells of the body. Using the network of arteries, veins and capillaries, blood carries carbon dioxide to the lungs (for exhalation) and picks up oxygen. From the small intestine, the blood gathers food nutrients and delivers them to every cell.

If you stopped breathing, or your lungs otherwise failed, the body would divert most of the oxygenated blood to the brain and heart (the most important organs), but that would only last a while, and eventually the brain would force the diaphragm to move, and you to breathe.
