Disorders of the Respiratory System -

 

  • Emphysema: The word “emphysema” means “inflation” or “full of air”. Emphy­sema is inflation or abnormal distension of the bronchioles or alveolar sacs of the lungs. Major causes are cigarette smoking and the inhalation of smoke or toxic substances over a period of time. As the alveolar septa collapse, the surface area for gas exchange is greatly reduced. There is loss of elasticity in the walls of bronchioles or alveolar sacs. As a result, the alveolar sacs remain filled with air even after expiration. The exhalation becomes more difficult. The lungs remain inflated. 

 

Hence, the correct option is There is inflation of the bronchioles or alveolar sacs of the lungs in emphysema
