Emphysema

Paper Summary:

Emphysema, also called pulmonary emphysema, is an abnormal distention of the lungs with air; in patients with emphysema, the air ducts and the air sacs, or alveoli, are distended, and there is destruction of the partitions between alveoli and loss of alveoli. This paper provides an overview of the disease, its etiology, treatment, and possible prevention modalities. A summary of the research is provided in the conclusion.

From the Paper:

"Many people with emphysema also have chronic bronchitis, in which inflammation and swelling of bronchial walls obstructs air flow. It is characterized by coughing due to excessive mucus in the airways. The two disorders are grouped together under the heading chronic obstructive pulmonary disease (COPD), which afflicts nearly 15 million people in the United States. According to Burri (2003), lungs affected by emphysema show loss or degeneration of elastic tissue, disappearance of capillary walls, and breakdown of the alveolar walls."
