从正常人主支气管的粘膜下腺体上进行了图形重建，显示了以前没有描述过的集合管。纤毛呼吸上皮浸入腺体开口，排列在导管的第一部分纤毛导管内，然后在集合导管内让位于由高柱状嗜酸性细胞组成的上皮，细胞内含有大量大线粒体。这种细胞结构表明集合管控制离子和水的浓度。从集合管中产生分泌小管，其上排列着粘液细胞--粘液小管。由浆液细胞排列的小管-浆液小管-从粘液小管的末端或侧面产生。
A graphic reconstruction has been made of a submucosal gland from a normal human main bronchus, revealing a collecting duct not previously described. Ciliated respiratory epithelium dips into the gland opening to line the first part of the duct, theciliated duct, and then gives way, in thecollecting duct, to an epithelium composed of tall, columnar, eosinophilic cells containing numerous large mitochondria. This cell structure suggests that the collecting duct controls ionic and water concentration. From the collecting duct arise secretory tubules lined by mucous cells—mucous tubules. Tubules lined by serous cells—serous tubules—arise from mucous tubules either terminally or laterally.
