Emphysema is a serious medical condition that occurs when the lungs become larger and do not work properly, causing difficulty in breathing. a serious disease that affects the lungs, making it difficult to breathe (from emphysan ). or pulmonary emphysema Abnormal distension of the lungs with air, usually associated with cigarette smoking and chronic bronchitis. Elastic tissue degenerates, severely interfering with exhalation. Capillary walls disappear, leaving lung tissue dry and pale. The walls of the pulmonary alveoli (see pulmonary alveolus) break down, so the lung fills with pools of air. Symptoms include severe breathlessness, weight loss, bluish skin, chest tightness, and wheezing. In bullous emphysema, the alveoli form large air cysts that may rupture, causing lung collapse (see atelectasis), or require surgery. Emphysema is irreversible; it normally continues to progress even after the cessation of smoking and may lead to death. See also pulmonary heart disease
Emphysema is a non-reversible pulmonary disease causing extreme shortness of breath and eventual death In this disease, the bronchial tubes of the lungs become blocked with mucus plugs and infection, inhibiting passage of air into and out of the aveoli (air sacs) The disease is characterized by destruction of these sacs which lose their elasticity, swell and rupture thereby interfering with the exchange of oxygen and carbon dioxide in the breathing process Emphysemais often caused by smoking
A lung disease in which tissue deterioration results in increased air retention and reduced exchange of gases The result is difficult breathing and shortness of breath It is often caused by smoking
A chronic pulmonary disease marked by an abnormal increase in the size of air spaces distal (farthest from the centre) to the terminal bronchioles with destructive changes in their walls (CMD 1997)
An abnormal accumulation of air in tissues , especially the lungs. Pulmonary emphysema is a chronic lung disease, characterised by an abnormal increase in the size of the air spaces, resulting in laboured breathing and caused by exposure to toxic chemicals such as tobacco smoke
A disease in which the walls of the air sacs (alveoli) are weakened or destroyed Emphysema results in lungs that are bigger than normal, cannot empty air normally and are unable to transfer oxygen efficiently into the bloodstream
Walt's Emphysema Q/A Archive Walt's Emphysema and Rebounding Article A pathological accumulation of air in tissues or organs, applied especially to such a condition of the lungs
the destruction, or breakdown, of the walls of the alveoli located at the end of the bronchial tubes The damaged alveoli are not able to exchange oxygen and carbon dioxide between the lungs and the blood The bronchioles lose their elasticity and collapse during exhalation, trapping air in the lungs The trapped air keeps fresh air and oxygen from entering the lungs
The presence of air in the alveolar tissue of the lungs It is caused when damage to the alveoli allows air to penetrate the interstitial tissue which then inflates
A condition of the lung characterized by increase beyond the normal in the size of the alveoli, with destructive changes in their walls and reduction of their number Clinical manifestations include "barrel chest" (increased anteroposterior diameter), prolonged expiration, and increased residual volume
A condition characterized by the destruction of the walls of airspaces which result in permanently abnormal enlarged air spaces This condition decreases the amount of lung surface available for the uptake of oxygen The resistance to air flow in the air passages is increased requiring more breathing effort Severe emphysema is characterized by a profound sense of breathlessness
Irreversibly diseased lung condition in which the alveolar walls have lost their resiliency, resulting in an excessive reduction in the lungs' capacity
(em-fi-sema) A chronic pulmonary disease characterized by degeneration/destruction of lung tissue This disorder is both hereditary and environmental, and is common in smokers
