..........•● Emphysema ●•...........

#Definition
⁃ Abnormal enlargement of air spaces distal to the terminal bronchioles characterized by destruction of the alveolar septa with little or no fibrosis


#Causes
• Inhalation
• Cigarette smoking and
environmental pollutants
• Infections
• Genetic factors

#Note
The Emphysema leads to
- loss of lung parenchyma
- loss of elastic recoil
