Bronchial secretion forms a periciliary liquid layer and may also give rise to thicker secretion that moves on the tips of the cilia. This latter material as collected at bronchoscopy or coughed up as sputum is a viscoelastic substance behaving in a characteristic way over a wide range of shear rates. The anatomical basis of secretion is described and its control as established by organ culture.
支气管分泌物形成纤毛周围液体层,也可能产生更浓稠的分泌物,这些分泌物在纤毛顶端移动。在支气管镜检查时收集的或作为痰液咳出的后一种物质是一种粘弹性物质,在很宽的剪切速率范围内表现出独特的行为。本文描述了分泌物的解剖学基础及其通过器官培养确定的调控机制。
