emphysema [(em-fuh-see-muh, em-fuh-zee-muh)]

A chronic disease in which the tiny air sacs in the lungs become stretched and enlarged, so that they are less able to supply oxygen to the blood. Emphysema causes shortness of breath and painful coughing and can increase the likelihood of developing heart disease. Emphysema occurs most frequently in older men who have been heavy smokers.
