Emphysema is a long-term, progressive disease of the lungs that primarily causes shortness of breath. Subcutaneous emphysema is a condition when gas or air is present in the subcutaneous layer of the skin.

In people with emphysema, the tissues necessary to support the physical shape and function of the lungs are destroyed. It is included in a group of diseases called chronic obstructive pulmonary disease or COPD (pulmonary refers to the lungs). Emphysema is called an obstructive lung disease because the destruction of lung tissue around smaller sacs, called alveoli, makes these air sacs unable to hold their functional shape upon exhalation. Emphysema is most often caused by tobacco smoking and long-term exposure to air pollution.

The term "emphysema" is derived from the Greek ἐμφυσᾶν emphysan meaning "inflate" - itself composed of ἐν en, meaning "in", and φυσᾶν physan, meaning "breath, blast".

Famous quotes containing the word emphysema:

    the small town big shot who, although very short,
    who although with a cigarette-stained mustache,
    who although famous for lobster on the rocks,
    left me here, nubkin, sucking in my vodka
    and emphysema cigarettes, unable to walk
    your walks, unable to write your writes.
    Anne Sexton (1928–1974)
