What Are The Most Common Lung Diseases?

Lung disease describes any issue that occurs in the lungs that inhibits them from functioning as they should. The lungs are an element of an intricate mechanism that relaxes and expands thousands of times a day to perform the oxygen and carbon dioxide exchange. Oxygen is essential for the cells throughout the body to operate properly. Lung diseases are the result of issues that occur within this mechanism.

There are three different subclasses of lung diseases. Lung tissue diseases are those that alter or have adverse effects on the structure of the lung. Airway diseases have adverse effects on the tubes that carry oxygen in and carbon dioxide out of the lungs.
