J98.4: Other disorders of lung

The lungs are on the left and right side of the ribcage. They are also connected to the nose and mouth via the bronchial tubes and windpipe (trachea).

You need lungs to breath. When you breathe in, the air with the oxygen passes through the airways to the lungs. The respiratory tract ends in the air sacs in the lungs. Oxygen passes into the blood in the pulmonary alveoli (air sacs). The pulmonary alveoli and the airways are surrounded by supportive tissue. This supportive tissue consists of connective tissue.

Something has changed in your lungs.
