1. A pathological condition of the lungs marked by an abnormal increase in the size of the air spaces, resulting in labored breathing and an increased susceptibility to infection. It can be caused by irreversible expansion of the alveoli or by the destruction of alveolar walls.
2. An abnormal distension of body tissues caused by retention of air.
[Greek emphūsēma, inflation, from emphūsān, to blow in : en-, in; see en-2 + phūsān, to blow (from phūsa, bellows, bladder).]

A chronic disease in which the small air sacs of the lungs (called alveoli) become enlarged and eventually collapse, causing blockage to the flow of air. Symptoms include difficulty breathing and loss of physical endurance. Emphysema can be caused by excessive smoking.
The American Heritage® Student Science Dictionary, Second Edition. Copyright © 2014 by Houghton Mifflin Harcourt Publishing Company. Published by Houghton Mifflin Harcourt Publishing Company. All rights reserved.
A disease in which the alveoli (tiny air sacs) of the lungs are damaged. Their separating walls are destroyed and the alveoli are enlarged. This leads to a decrease in the surface area available for gas exchange, and breathing becomes very difficult. The major cause of emphysema is tobacco smoking, but pollution and hereditary factors may also be involved.
