Every cell in your body inhales the oxygen and exhales the carbon dioxide – a process called respiration. Breathing isimportant because our cells constantly need a new supply of oxygen so they can produce energy – without this vital oxygen, cellular function is impaired, and damage or cell death is possible.While breathing in we take oxygen from air. This oxygen goes into the blood stream and reacts with glucose and produce energy. So despite taking variety of foods,we won’t get any energy from them,if we don’t breathe. Because for the oxidization of glucose,oxygen is required.
No, we have to breath to live, our bodies need oxygen.
