Question

Quizplus · Accepted Answer

Pneumoconiosis is a chronic lung disease caused by the inhalation of mineral dust particles such as silica, asbestos, and mica. These particles can accumulate in the lungs and cause inflammation, fibrosis, and decreased lung function. Autoimmune disease and allergic reactions are not typically associated with the development of pneumoconiosis. Flail chest is a condition where there is movement of a segment of the chest wall due to multiple rib fractures and is not related to the development of pneumoconiosis.
