The Lungs! IF YOU STOPPED BREATHING.............. If you stopped breathing, for more than a minute or two, you would quickly die. Breathing provides your blood with the oxygen from the air that is vital to the survival of every body cell. Just as fire burns only if there is plenty of oxygen, so body cells need oxygen from the blood to break down the food they also get from the blood. Without oxygen, brain cells live only a few minutes, which is why the brain is quickly damaged if the heart stops pumping blood. When cells break down food, oxygen joins with carbon in the food to make carbon dioxide, which you breathe out.
