Options
A.Emphysema: reduction of suface area of alveoli and bronchi
B.Pneumonia: occupational disease with asbestos
C.Silicosis: inflammation of alveoli
D.Asthma: excessive secssive secretion of bronchil mucus
Solution
Cigarette smoking leads to the diseas emmhysema. In this disease, terminal bronchi oles get obstructed this reduces the ventilation of the aveoli connected to them. many alveoli coalesce together to form large chambers due to destruction of their walls. This change of amaller alveoli to large chambers reduces the area of aleolar surface across which gases are exchanged. all these changes reduce both pxygen uptake and carbon dioxide elimination.
