细支气管:肺内较小的气道分支,连接支气管与肺泡,主要负责将空气输送到进行气体交换的区域。(在解剖学中也可细分为终末细支气管、呼吸性细支气管等。)
/ˈbrɒŋkiəʊl/(BrE), /ˈbrɑːŋkioʊl/(AmE)
The doctor said my bronchioles were inflamed.
医生说我的细支气管发炎了。
During an asthma attack, the smooth muscles around the bronchioles can tighten, making it difficult to breathe.
在哮喘发作时,细支气管周围的平滑肌可能收缩,从而导致呼吸困难。
bronchiole 来自 bronchi-(与“支气管”相关,源自希腊语 brónkhos,意为“气管/喉部”)+ 指小后缀 -ole / -iole(表示“较小的”)。整体意思就是“较小的支气管分支”。
