What is eniphysema?

Answer 1

Emphysema is a chronic respiratory condition characterized by the damage and destruction of the alveoli, the small air sacs in the lungs where gas exchange occurs. This damage leads to reduced elasticity of the lung tissue, making it difficult for patients to exhale air fully, resulting in shortness of breath and decreased oxygen supply to the body. Emphysema is most commonly caused by long-term exposure to irritants such as cigarette smoke, air pollution, or occupational dust. It is a major component of chronic obstructive pulmonary disease (COPD).
