COPD, which stands for Chronic Obstructive pulmonary Disease, is a category of lung diseases that includes chronic bronchitis (emphysema), asthma and chronic bronchitis.

This makes it difficult to exchange air between alveoli, blood vessels, and air sacs. The result is lower oxygen levels throughout the body. Chronic exposure to irritating substances such as cigarettes can result in damage to the ciliated cells that line your lungs. In turn, this can reduce airflow and impair mucociliary clearance. It can also lead to an increase in mucus production. Small airway passages can become blocked by it. These factors combined lead to common signs & symptoms associated with COPD including shortness of breath, wheezing, persistent cough with sputum production, tight chest feeling etc..
