J62: Pneumoconiosis due to dust containing silica

J62.8: Pneumoconiosis due to other dust containing silica

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.

You have inhaled a lot of dust-containing silica over a considerable time. This dust has been deposited in your lungs.

The dust in your lungs has activated your immune system. The immune system has caused an inflammation. The pulmonary alveoli, or air sacs, were damaged by the inflammation.

The immune system can also release substances by which the connective tissue in the lungs multiplies. As a result, the wall of the pulmonary alveoli thickens. When the wall of the air sacs is thickened, less oxygen from the lungs is able to get into the blood.
