粘液纤毛对微尘的清除功能是呼吸道的主要防御机制,纤毛所产生的方向一致的协调滑动使粘液呈单向流动。新近人们认为,不规则的纤毛运动可能是原发性纤毛运动障碍(PCD)的变异,这类病人的纤毛超微结构及滑动频率(CBF)正常或接近正常,
Mucous cilia on the removal of dust is the main respiratory defense mechanism, the direction of the cilia generated by the coordinated sliding of the mucus was one-way flow. Recently, people think that irregular ciliary motility may be a variation of primary ciliary dyskinesia (PCD). These patients have normal or near-normal ciliary ultrastructure and gliding frequency (CBF)
