The disease occurs because cigarette smoke stimulates the airways, causing airway inflammation. When inflamed, the airways will secret more sputum, the feathers used to move dirt out of the lungs is paralyzed and destroyed, so smokers more prone to colds, sore throats, bronchitis and pneumonia than people who do not smoke.

Chronic obstructive pulmonary disease

Chronic inflammation in the lungs makes inflammatory cells flock to secrete substances that destroy lung tissue.
