呼吸性细支气管

病理形态特点是呼吸性细支气管全层受累。

Pathologically , all layers of the respiratory bronchiole walls were involved .

全腺泡型肺气肿发生时则出现从呼吸性细支气管到肺泡的腺泡所有部分全部扩张。

Panacinar emphysema occurs with loss of all portions of the acinus from the respiratory bronchiole to the alveoli .

结果DPB是一种慢性小气道疾病，以两肺弥漫性呼吸性细支气管的炎症为特征。

Results DPB is a chronic lower respiratory tract disease common in Japanese , rare in China , characterized by infiltration of inflammatory cells around bronchioles .

呼吸性细支气管末端有括约肌。

The end of the respiratory bronchiole has a sphincter .

呼吸性细支气管水平及肺泡水平小动脉肌化。

The muscularized arteries were observed at the level of both respiratory bronchioles and alveoli .

随胎龄增加，叶支气管、小支气管、细支气管、终末细支气管、呼吸性细支气管和肺泡导管管壁的粘膜上皮间均可见阳性细胞。

With the development , these cells could be seen in the epithelium of bronchi , bronchioles and alveolar ducts .

对86例煤工尸检肺组织呼吸性细支气管及所属肺泡道发生的尘斑气肿进行了观察。

Morphological observations on dust-maculae-emphysema occurred on respiratory bronchiole and alveolar track in 86 autopsy cases of coal workers were performed .

肺微血管构筑可区分出呼吸性细支气管范围、肺泡管范围，以及肺泡范围3级微血管单位。

According to the microvascular architecture , the pulmonary microvasculature may be divided into three ordered units : i. e. the alveolar , the alveolar duct , and the respiratory bronchiolar units .

结果发现哮喘组肺内支气管及细支气管阳性纤维增粗、分布密集度显著增加：在呼吸性细支气管及肺泡亦偶有分布；有部分阳性纤维经粘膜上皮内伸出并暴露于管腔内。

The result showed a thick and dense distribution of bronchus and bronchiole of asthma group ; a sparse distribution in respiratory bronchiole and pulmonary alveoli ; some positive fibers extrude the epithelium mucosae into the alveoli .

煤矿工人慢性支气管炎最显著的特点是在各级支气管管壁有粉尘沉积和尘细胞浸润，支气管壁周围可有尘性纤维化，特别是在呼吸性细支气管处尘性病变最重。

The most apparent features of chronic bronchitis in coal miners include dust deposition and dust cell infiltration on the walls of bronchi at all levels , and dust fibrosis around the bronchial walls , with the most severe pathological change of dust deposition on the respiratory bronchiole .

呼吸部肺泡数多，每支呼吸性细支气管分出68支肺泡管，肺泡较小，处于半充容状态。

Respiratory region has a great number of alveolar ducts . There are 6 to 8 alveolar ducts in each of pneumatic bronchiole . Alveolus is rather small and semi-full .
