Centrilobular emphysema occurs with loss of the respiratory bronchioles in the proximal portion of the acinus, with sparing of distal alveoli.
当腺泡近端的呼吸性细支气管扩张，而远端的肺泡扩张不明显，腺泡中央型肺气肿就会发生。
The incidence of centrilobular emphysema, paraseptal emphysema and air trapping in heavy smokers was higher than that in light ones ( P< 0.05).
小叶中心型肺气肿、间隔旁型肺气肿和空气潴留在重度吸烟组的发生率高于轻度吸烟组（P< 0 .0 5 ）。
