Diseases That Affect The Lungs

Lungs are the most crucial organ of our body that expand and relax multiple times daily for expelling the carbon dioxide from the body and inhaling the oxygen. Problems in any part of the lungs can lead to lung diseases. The windpipe or trachea branches into two tubes which are called bronchi that in return branch out to million small tubes that pass throughout the lungs. The cells of the body need oxygen for their functioning and that oxygen is provided to the body by the lungs. Lungs throw the oxygen in the blood stream and take out the carbon dioxide. Normally an individual breathes almost 25,000 in a day but people suffering from lung disease experience difficulty in breathing. Some of the common diseases that affects lung are:
