Mucus is thick and slippery and secreted by your body’s glands and cells. Overproduction, hypersecretion, and decreased clearance of phlegm make mucus accumulate in the lungs.
Commonly, your body will tell your cells to produce and secrete mucus as a result of environmental irritants. If you smoke, the cilia or tiny hair-like structures in your lungs become damaged, and cilia are responsible for clearing mucus.
Damaged cilia are unable to clear mucus, so the mucus remains stuck in your airways.
