The type of bronchitis that causes no permanent damage to the lungs and lasts for two weeks is known as:
Correct answer: A. Acute bronchitis
- A. Acute bronchitis
- B. Chronic bronchitis
- C. Coastal bronchitis
- D. Intercostal bronchitis
Explanation
'Acute bronchitis' is a contagious viral infection that causes inflammation of the bronchial tubes - these are the airways that carry air into your lungs. When these tubes get infected, they swell and Mucus (thick fluid) forms inside them. This narrows the airways, making it harder for you to breathe. But it lasts for a few weeks and its effects can be reversed. Thus, option A is correct.

About Respiration
The human respiratory system includes the air passages, lungs, alveoli and breathing muscles, while gaseous exchange explains how oxygen enters blood and carbon dioxide leaves it by diffusion. The effects of smoking include damage to cilia and alveoli, reduced gas exchange, chronic bronchitis, emphysema and increased risk of lung cancer.
