In healthy individuals, alveoli are hollow plump air sacs where gas exchange occurs. They look like an upside down grapes on a stem. In emphysema, the alveoli become flattened or collapse.
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 or Pulmonay emphysema
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.
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.
