Emphysema is a long-term, progressive disease of the lungs that primarily causes shortness of breath due to over-inflation of the alveoli (air sacs in the lung). In people with emphysema, the lung tissue involved in exchange of gases (oxygen and carbon dioxide) is impaired or destroyed.Source: emedicinehealth :)
Emphysema is a lung condition in which tiny air sacs in the lungs - alveoli - fill up with air. As the air continues to build up in these sacs, they expand, and may break or become damaged and form scar tissue.
Emphysema is a disease that destroys the tiny air sacs in your lungs. In this case it can even cause lung cancer. A person with advanced emphysema uses 80% of his/her energy to breathe.
It reduces the surface area because it reduces the number of alveolar sacs in a persons lungs.

Emphysema is a disease that involves the breakdown of the air sacs in the lungs. This condition is typically a result of long-term exposure to irritants such as cigarette smoke, leading to damage and destruction of the alveoli. Emphysema can result in difficulty breathing and reduced lung function.

Alveoli are the tiny air sacs that look like hollow plump grapes in healthy people. In emphysema, many of the alveoli collapse so there is less surface area for gas exchange.
