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.
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.

Emphysema is a condition where there are little holes in the air sacs in the lungs. It is usually caused by excessive smoking.

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.
It reduces the surface area because it reduces the number of alveolar sacs in a persons lungs.

William Higginbotham died from emphysema, a condition in which the air sacs of the lungs are damaged and enlarged, causing breathlessness.
i think your meaning emphysema. Emphysema is a lung disorder . See you have tiny air sacs in your lungs called Alevioli and what they do is they fill up with air and it takes the oxygen out and then excretes carbon dioxide and goes into your lungs and then is exhailed . In emphysema these tiny sacs explode and deteriorate. so there are less of them to use which means your lungs have to work harder and harder to get the adequate oxygen your body needs to work. This disease is characterized by shortness of breath trouble breathing coughing and in some cases coughing up blood.
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 :)
