Question

Name the chronic respiratory disorder caused mainly by cigarette smoking.
A. Emphysema
B. Asthma
C. Respiratory acidosis
D. Cough

Answer 1

Hint: Cigarette smoking is as always stated injurious to health because it leads to permanent alveolar damage leading to disturbance is the exchange of gases between the lungs and blood vessels. This leads to difficulty in breathing and improper distribution of oxygen to body tissues.

Complete answer:
Option-A: Emphysema
It may be stated as a chronic disorder i.e. persistent for life. This type of disease may occur due to over or persistent exposure to any smoking material such as smoking cigarettes leading to the destruction of alveoli and decreasing the area of gaseous exchange.
Option-B: Asthma
First of all, it may be an acute or chronic disorder depending on the exposure of the respiratory tract to foreign particles. These particles cause obstruction of bronchioles causing difficulty in breathing.
Option-C: Respiratory acidosis
This condition is caused due to impairment of the lungs to release carbon dioxide from the body. It is a secondary disease caused due to any primary disease which affects the function of the lungs such as COPD, asthma, neuromuscular damage, etc.
Option-D: Cough
It is an acute disease. It is caused due to inhalation of irritants such as dust or any particle causing irritation in the respiratory tract and the body initiates cough reflex to eliminate it.

So, the correct answer to this question is the option “A” Emphysema.

Note: Respiratory disorders are caused due to problems caused in the respiratory tract due to the invasion of any foreign particle. These may be acute or chronic. These diseases caused can be occupational also.
