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: -Pulmonary emphysema is part of a group of lung diseases called COPD (chronic obstructive pulmonary disease). COPD lung diseases cause airflow blockage and breathing problems. The 2 most common conditions of COPD are chronic bronchitis and emphysema.

Detailed explanation-3: -Emphysema develops over time and involves the gradual damage of lung tissue, specifically the destruction of the alveoli (tiny air sacs). Gradually, this damage causes the air sacs to rupture and create one big air pocket instead of many small ones.

Detailed explanation-4: -(EMP-fuh-ZEE-muh) A disorder affecting the alveoli (tiny air sacs) of the lungs. The transfer of oxygen and carbon dioxide in the lungs takes place in the walls of the alveoli. In emphysema, the alveoli become abnormally inflated, damaging their walls and making it harder to breathe.

Detailed explanation-5: -COPD (chronic obstructive pulmonary disease) is a common preventable and treatable disease of the lungs. Patients with COPD have airflow obstruction that is caused either by destruction of the air sacs that exchange gas in the lungs (emphysema) and/or inflammation of the airways (chronic bronchitis).
