Pathology, pathogenesis, and pathophysiology - PMC
Chronic obstructive pulmonary disease (COPD) is characterised by poorly reversible airflow obstruction and an abnormal inflammatory response in the lungs. The latter represents the innate and adaptive immune responses to long term exposure to noxious particles and gases, particularly cigarette smoke.

Chronic Obstructive Pulmonary Disease (COPD) - Pulmonary …
Chronic obstructive pulmonary disease (COPD) is airflow limitation caused by an inflammatory response to inhaled toxins, often cigarette smoke. Alpha-1 antitrypsin deficiency and various occupational exposures are less common causes in patients who do not smoke.
Diagnosing COPD • Clinical presentation • Airflow obstruction without reversibility • Exclilusion of alilternative causes – Asthma – Bronchiecatasis (e.g., cystic fibrosis) – Congestive heart failure – Tuberculosis – Other causes of airflow obstruction
