Explanation:
Detailed explanation-1: -Emphysema is a lung condition that causes shortness of breath. In people with emphysema, the air sacs in the lungs (alveoli) are damaged. Over time, the inner walls of the air sacs weaken and rupture-creating larger air spaces instead of many small ones.
Detailed explanation-2: -In the past 30 years, the prevailing concept to explain emphysema development has relied on lung inflammation caused by cigarette smoke, environmental pollutants, or bacterial products, leading to a protease/antiprotease imbalance (1), which ultimately would cause alveolar destruction in emphysema.
