The tiny hairs that keep mucus and dirt out of your lungs are called cilia. Cilia are microscopic, hair-like structures that line the respiratory tract. They play a crucial role in the respiratory system's defense mechanism. By beating in a coordinated fashion, cilia help to move mucus, which traps dirt, dust, and pathogens, upwards toward the throat. This movement aids in clearing these unwanted particles from the airways, helping to maintain clean and clear lungs. If the cilia become damaged or dysfunction, it can lead to ineffective clearing of mucus and an increased risk of respiratory infections. Hence, cilia are essential for respiratory health.
