MICROANATOMY

Detailed explanation-1: -If you have COPD, less air flows in and out of your airways because of one or more problems: The airways and air sacs in your lungs become less elastic. The walls between many of the air sacs are destroyed. The walls of the airways become thick and inflamed.

Detailed explanation-2: -In COPD, the airways of the lungs (bronchial tubes) become inflamed and narrowed. They tend to collapse when you breathe out and can become clogged with mucus. This reduces airflow through the bronchial tubes, a condition called airway obstruction, making it difficult to move air in and out of the lungs.

Detailed explanation-3: -Symptoms include breathing difficulty, cough, mucus (sputum) production and wheezing. It’s typically caused by long-term exposure to irritating gases or particulate matter, most often from cigarette smoke. People with COPD are at increased risk of developing heart disease, lung cancer and a variety of other conditions.

Detailed explanation-4: -Chronic lower respiratory disease, primarily COPD, was the fourth leading cause of death in the United States in 2018.

Detailed explanation-5: -Bronchitis affects the bronchial tubes in your lungs. It irritates them and then the tubes swell. Chronic bronchitis is the condition that causes COPD. Emphysema affects how your lungs transfer oxygen into your bloodstream. Asthma is not a condition that causes COPD, but you can have asthma and COPD. 18-Mar-2021
