alveolar ducts

Alveoli form clusters ( alveolar sacs ) connected by alveolar ducts to the Bronchioles.

肺泡形成丛集的肺泡囊,经由肺泡管连接至支气管.

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.

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。

RESULTS: In diabetic rats, the iNOS positive or weak positive staining was localized in epithelial cells of bronchi, epithelial cells of alveolar ducts, alveolar sacs, and arteries, but negative in endothelial cells of vein and capillary.

结果：糖尿病4周大鼠肺支气管上皮细胞、肺泡管上皮细胞、肺泡囊上皮细胞和动脉内皮细胞iNOS呈阳性或弱阳性，静脉内皮细胞、毛细血管内皮细胞iNOS呈阴性。

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

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。
