Detailed explanation-1: -Chronic obstructive pulmonary disease (COPD) happens when the lungs and airways become damaged and inflamed. It’s usually associated with long-term exposure to harmful substances such as cigarette smoke.
Detailed explanation-2: -COPD is usually caused by cigarette smoking, though long-term exposure to other lung irritants, like secondhand smoke, can also contribute to COPD. As many as 1 out of 4 Americans with COPD never smoked cigarettes.
Detailed explanation-3: -When a cigarette burns, it creates more than 7, 000 chemicals, many of which are harmful. The toxins in cigarette smoke weaken your lungs’ defense against infections, narrow air passages, cause swelling in air tubes and destroy air sacs-all contributing factors for COPD.
Detailed explanation-4: -What is COPD? Chronic obstructive pulmonary disease, or COPD, refers to a group of diseases that cause airflow blockage and breathing-related problems. It includes emphysema and chronic bronchitis.
