1·Panacinar emphysema occurs with loss of all portions of the acinus from the respiratory bronchiole to the alveoli.
发生全肺气肿时，从呼吸性细支气管到肺泡的所有腺泡都丢失了。
2·Within the lungs, the mucus-lined bronchi split like the branches of a tree into tens of thousands of ever smaller tubes (bronchioles), which connect to tiny sacs called alveoli.
在肺部，布满粘液的支气管像树一样又分为成千上万个更小的管(细支气管)，他们连接到叫做肺泡的小囊。
3·In these cases the virus rapidly destroys the lungs' alveoli, where gas transfer occurs, often causing acute respiratory distress syndrome (ARDS), which usually kills in half of all cases.
在这些病例中，流感病毒能迅速破坏肺泡，影响氧气转换，这往往会造成急性呼吸窘迫症（ARDS），有一半病例因此而死亡。
4·The lungs are made up of small sacs called alveoli, which fill with air when a healthy person breathes.
肺由称为肺泡的小气囊组成，当健康的人呼吸时会充满空气。
5·There are enough alveoli in just one lung to cover an area roughly the size of a tennis court.
一个肺叶里的肺泡就足够覆盖住网球场大小的面积。
