The conduction of air in and out of the body is known as ventilation.Since the question asks for the body's mechanism,this would be spontaneous ventilation.External respiration involves the exchange of oxygen (O₂)and carbon dioxide (CO₂)between the alveoli and the pulmonary capillaries.Internal respiration occurs at the cellular level and involves movement of oxygen from the systemic blood into the cells.
