Question

Respiratory disorder due to excessive pollution resulting in collapse and alveolar breakdown is:

• A. Emphysema
• B. Hydrothorax
• C. Cyanosis
• D. All of the above

Answer 1

The correct option is A Emphysema

Emphysema is another chronic obstructive pulmonary disease.As in this condition, the inner walls of the air sac get ruptured creating larger air space. This reduces the surface area of the lungs and thus, reduces the amount of oxygen to reach the bloodstream. Patients initially experience bouts of breathlessness and coughing, and their ability to be active becomes very limited. Eventually, the alveoli become permanently damaged, and whole regions of the lung are unable to be engaged in the gas exchange with the blood. The most common cause of emphysema is cigarette smoking (80-90% of emphysema cases) and pollution. Thus, the correct answer is option A.
