on. Since the question asks for the body’s mechanism, this would
s1 s1 s1 s1 s1 s1 s1 s1 s1 s1 s1


be spontaneous ventilation. External respiration involves the exch
s1 s1 s1 s1 s1 s1 s1


ange of oxygen (O2) and carbon dioxide (CO2) between the alveoli
s1 s1 s1 s1 s1 s1 s1 s1 s1 s1 s


and the pulmonary capillaries. Internal respiration occurs at the

cellular level and involves movement of oxygen from the systemic
s1 s1 s1 s1 s1 s1 s1 s1 s1


blood into the cells.
