What is emphysiema?

Answer 1

Emphysema is a chronic lung condition that involves the destruction of the alveoli, the small air sacs in the lungs responsible for gas exchange. This damage results in reduced airflow and difficulty breathing, primarily due to the loss of elasticity in the lung tissue. Emphysema is often caused by long-term exposure to irritants such as cigarette smoke, air pollution, or occupational dust and chemicals. It is a key component of chronic obstructive pulmonary disease (COPD) and can significantly impact the quality of life.
