Alpha-1 Lung Vocabulary

Bullous Lungs

Emphysema begins with the destruction of air sacs (alveoli) in the lungs where oxygen from the air is exchanged for carbon dioxide in the blood. The walls of the air sacs are thin and fragile. Damage to the air sacs is irreversible and results in permanent "holes" in the tissues of the lower lungs ,which is often referred to as "bullous lungs".

As air sacs are destroyed, the lungs are able to transfer less and less oxygen to the bloodstream, causing shortness of breath. The lungs also lose their elasticity. The patient experiences great difficulty exhaling.

Bullous lungs in general:

  • Enlarge progressively over a period of months or years
  • Most are associated with emphysema
  • May become infected or lead to pneumothorax

In terminology:

  • One is bulla
  • Two or more are bullae (pronounced "bully")
  • Diseases which contain bullae are bullous diseases
