how do you process the air you breathe before it gets to your lungs?
 The process of breathing involves the exchange of gases, namely, oxygen and carbon dioxide that occurs between you, in particular, the cells of your body, and the outside environment, which is the air. This exchange happens in the lungs. In all, breathing has two components: Ventilation, or movement of oxygen into, and carbon dioxide, out of your lungs. Circulation, or transporting the oxygen taken into the body during ventilation to where it is needed in the body. In terms of how breathing can enhance your therapeutic back exercise program or your successful participation in a pro-active holistic therapy, it's the ventilation component that takes center stage.
