Breathing is a fundamental life process that usually occurs without conscious thought and, for the healthy person, is taken for granted. It involves: The coordinated action of inspiratory and expiratory muscles; The unimpeded passage of air from the atmosphere through the upper to the lower respiratory tract; The exchange of oxygen (O2) and carbon dioxide (CO2) across the alveolar membrane.
