Question

Respiratory disorder in which the walls of alveoli is damaged is called ____.

• A. asthma
• B. emphysema
• C. bronchitis
• D. lung cancer

Answer 1

The correct option is B

emphysema

Emphysema is a lung condition that causes shortness of breath and alveoli ruptures or damage due to the loss of elasticity, by the deposition of toxic substances contained in tobacco. This reduces the respiratory surface and reduces the vital capacity of the lungs. Whereas lung cancer is the uncontrolled growth of abnormal cells that start off in one or both lungs usually in the cells that line the air passages. Bronchitis is an inflammation of the lining of your bronchial tubes, which carry air to and from your lungs. Asthma is a condition in which your airways narrow and swells and produce extra mucus Which results in difficulty in breathing.
