Emphysema. Artwork showing the lungs with a detailed view of a normal alveolus (air sac,left) and an alveolus affected by emphysema (right). Emphysema is a disease in which the tiny air sacs (alveoli) of the lung become enlarged and the walls separating them are damaged. Surface area for gaseous exchange is reduced,restricting oxygen uptake. This may cause breathlessness,bluish skin,and heart or respiratory failure. Occurrence of emphysema is strongly associated with smoking | |
