Visitor's comment: Respiration is the release of energy from glucose or another organic chemical. Breathing is the process that moves air in and out of the lungs. Gas exchange takes place at a respiratory surface —a boundary between the external environment and the interior of the organism. Respiration occurs in cell. Gas exchange occurs in alveoli in lungs. Breathing occurs through the airways.
