Mucociliary clearance diagram
Mucociliary clearance (MCC), mucociliary transport, or the mucociliary escalator, describes the self-clearing mechanism of the airways in the respiratory system. It is one of the two protective processes for the lungs in removing inhaled particles including pathogens before they can reach the delicate tissue of the lungs. The other clearance mechanism is provided by the cough reflex. Mu… WebAirway clearance therapy (ACT) is a kind of airway physiotherapy and is indicated for patients with altered mucociliary escalator or compromised ability to expectorate …

WebBoth processes compromise mucociliary clearance. This loss of mucociliary transport renders the airways susceptible to microbial colonization. Neutrophils are also believed promote this process by allowing bacterial adherence to the lung epithelium. In response to this colonisation, a cycle of an intense chronic inflammatory response is triggered.
