Question

Asthma is a respiratory disease caused due to

• A. infection of lungs
• B. infection of trachea
• C. spasm in bronchial muscles
• D. bleeding in pleural cavity

Answer 1

The correct option is C

spasm in bronchial muscles

The correct option is C.

Explanation for Correct option:

1. Asthma is caused by inflammation in the airways that normally carry air in and out of the lungs.
2. This inflammation makes the trachea extremely sensitive, so it tends to narrow temporarily.
3. Typical symptoms of asthma include coughing, chest tightness, and difficulty breathing.
4. Asthma can occur randomly, or even from air pollutants entering the lungs after exposure to asthma triggers and air pollution from vehicles, chimneys, and factories.
5. the airways and lungs of a person can become obstructed because they become narrow and cut off airflow.
6. Bronchioles can also constrict (narrow) because of muscle spasms.

Final answer: Asthma is a respiratory disease caused due to spasms in bronchial muscles.
