Mucous secretions covering the surface of the trachea and major bronchi of the rabbit lung have been demonstrated with the scanning electron microscope. The surface secretion forms a continuous layer overlying the major airways and shows a complex 3-dimensional arrangement of overlapping sheets and fibrous networks. In the main and lobar bronchi, mucus forms more expanded networks, and in the trachea, mucus forms a smoother, more cohesive layer overlying the epithelial cells. The mucous blanket follows closely the contours of the airway epithelium and is situated at the tips of the cilia.
利用扫描电子显微镜已证实家兔肺气管和主支气管表面覆盖有黏液分泌物。表面分泌物在主要气道上形成连续层，呈现出重叠片层和纤维网络的复杂三维排列。在主支气管和叶支气管中，黏液形成更扩展的网络，而在气管中，黏液在覆盖上皮细胞上形成更光滑、更具黏性的层。黏液毯紧密跟随气道上皮的轮廓，并位于纤毛尖端。
