粘液纤毛清除系统(MC)是呼吸系统防御机制的重要组成部分,通过粘液纤毛清除系统的清除作用,保持呼吸道的正常生理功能。反之在多种因素影响下,粘液纤毛清除系统会出现一系列损伤,导致粘液纤毛清除能力下降,并进一步减弱传导性气道的免疫功能,造成呼吸系统的反复感染。因此在呼 Mucus Ciliary Clearance System (MC) is an important part of the respiratory defense mechanism that maintains the normal physiological function of the respiratory tract through the removal of mucociliary clearance system. Conversely, under a variety of factors, mucociliary clearance system will appear a series of damage, resulting in reduced mucociliary clearance, and further reduce the immune function of the conductive airway, causing repeated respiratory infections. So call
