The lungs play a critical role in ensuring our body receives the oxygen it needs while eliminating carbon dioxide. Thus, any pathology of the lungs can disturb the vital function, which causes pain, breathing disorders, and other severe conditions. There are lung disorders that are an annoyance and there are those that are long-standing and life-altering. Learning about the usual lung conditions, their cause, and when to see a pulmonologist, may help early detection of the diseases.
