Pathology, pathogenesis, and pathophysiology | The BMJ
May 18, 2006 · Besides inflammation, two other processes are involved in the pathogenesis of COPD—an imbalance between proteases and antiproteases and an imbalance between oxidants and antioxidants (oxidative stress) in the lungs.
Chronic Obstructive Pulmonary Disease (COPD)
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.
Two main biologic mechanisms can lead to chronic obstructive pulmonary disease (COPD) in adulthood: abnormal lung development and an increased rate of lung-function decline with age.

Pathophysiology of COPD - SpringerLink
Feb 12, 2020 · Chronic obstructive pulmonary disease (COPD) is a progressive inflammatory disease of the lung that involves complex interaction of cells and mediators. And it is characterized by progressive airflow limitation that is not fully reversible, which is caused by two...
pathological changes found in COPD. Pathogenesis Inflammation is present in the lungs, particularly the small airways, of all people who smoke. This normal protective response to the inhaled toxins is amplified in COPD, leading to tissue destruction, impairment of the defence mechanisms that limit such destruction, and disruption of the repair ...
Pathogenesis of COPD - SpringerLink
COPD is defined as a disease state characterized by progressive airflow limitation that is not fully reversible, which is caused by two pathologic processes resulted from chronic inflammation; narrowing of the small airways and emphysematous destruction of the lung parenchyma.
