Pulmonary Fibrosis

Under certain conditions, for reasons that are poorly understood, lung damage leads to pulmonary fibrosis instead of emphysema. In this condition, the normal structure of the lungs is disrupted by the accumulation of fibrous connective tissue proteins. Fibrosis can result, for example, from the inhalation of particles less than 6 |im in size that can accumulate in the respiratory zone of the lungs. Included in this category is anthracosis, or black lung, which is produced by the inhalation of carbon particles from coal dust.
