a. expansion of the diaphragm by 2 cm
b. expansion of the circumference of the thorax by 5–7 cm

d. increase in PaO2 and PaCO2 levels by 30%
B
To accommodate the increased oxygen consumption and carbon dioxide excretion, the diaphragm elevates approximately 4 cm, circumference of the thorax expands by 5–7 cm, and tidal volume increases by 30% to 40%. These physiological changes often lead to an increased respiratory rate, hyperventilation, or shortness of breath, especially on exertion.
