Quizplus · Accepted Answer

Pulmonary fibrosis is a condition in which normal lung tissue is gradually replaced with scar-forming fibrous connective tissue, leading to decreased lung function. Exposure to asbestos fibers or similar irritants is one of the main causes of pulmonary fibrosis. Pleurisy is inflammation of the membrane lining the lungs and chest cavity, chronic bronchitis is inflammation of the bronchi leading to a chronic cough, emphysema is destruction of the air sacs in the lungs, and asthma is inflammation and narrowing of the airways. None of these conditions involve the progressive scarring of lung tissue seen in pulmonary fibrosis.
