top: normal bronchiole and alveoli
bottom: diseased bronchiole with mucus, enlarged air sacs in the alveoli, and fewer capillaries
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).]

1. (Pathology) Also called: pulmonary emphysema a condition in which the air sacs of the lungs are grossly enlarged, causing breathlessness and wheezing
2. (Pathology) the abnormal presence of air in a tissue or part
[C17: from New Latin, from Greek emphusēma, a swelling up, from emphusan to inflate, from phusan to blow]
em•phy•se•ma(ˌɛm fəˈsi mə, -ˈzi-)
1. a chronic disease of the lungs characterized by difficulty in breathing due to abnormal enlargement and loss of elasticity of the air spaces.
2. any abnormal distention of an organ or part of the body with air or other gas.
[1655–65; < New Latin < Greek emphysēma=emphȳsē-, variant s. of emphȳsân to blow up, inflate + -ma n. suffix of result]
em`phy•sem′a•tous (-ˈsɛm ə təs, -ˈsi mə-, -ˈzɛm ə-, -ˈzi mə-) adj.
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.
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.
