J66: Airway disease due to specific organic dust

J66.0: Byssinosis

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.

The cotton contains substances that can irritate the lungs. You have symptoms in your lungs after inhaling dust from unprocessed cotton. These symptoms are most severe when you have had no contact with cotton for some days and then you come into contact with it once more.
