What is the primary characteristic of COPD?

1. Acute airway obstruction

2. Slow process of dilation and disruption of airways

3. Rapid onset of symptoms

4. Inflammation of alveoli only

The correct answer is: Slow process of dilation and disruption of airways

The primary characteristic of Chronic Obstructive Pulmonary Disease (COPD) is indeed the slow process of dilation and disruption of the airways. COPD is a progressive lung disease that encompasses conditions such as emphysema and chronic bronchitis. Over time, the airways and air sacs in the lungs undergo gradual changes, including inflammation, narrowing, and destruction, leading to reduced airflow and difficulty in breathing. This process often occurs due to long-term exposure to harmful substances, primarily cigarette smoke, but also includes pollutants and other irritants. The changes in the lung structure result in irreversible airflow obstruction, which typically worsens over time, emphasizing the chronic aspect of the disease. Patients usually experience symptoms such as chronic cough, sputum production, and dyspnea, but these symptoms develop more slowly compared to acute respiratory conditions, highlighting the gradual nature of this disease process.
