What natural defense mechanisms are usually effective at filtering PM10 particles?
Answer
The hairs in our nose and throat
The natural physical defenses of the upper respiratory system are generally efficient at preventing larger particulate matter from reaching the sensitive deep lung tissue. Specifically, the hairs located within the nose and throat serve as the primary filtering mechanism for PM10 particles, which are defined as having diameters of 10 micrometers or smaller. Because PM10 particles are relatively larger compared to their fine counterparts, these upper airway defenses manage to capture and filter them out before they can penetrate into the lower airways, where the risk of deeper systemic penetration increases significantly.
