Which organ is primarily involved in pneumoconiosis?

Pneumoconiosis is a type of lung disease that is caused by the inhalation of certain types of dust particles, leading to inflammation and scarring of lung tissue. It is commonly associated with occupational exposures to substances such as coal dust, asbestos, silica, and other hazardous materials. The primary organ affected by pneumoconiosis is the lung, as it is the site where these particulate matters are deposited, causing a range of respiratory issues, including coughing, shortness of breath, and chronic respiratory disease. The process involves the body's immune response to inhaled dust, which may lead to fibrotic changes in lung tissue, ultimately impairing respiratory function. This clear link between pneumoconiosis and the lungs highlights why this organ is specifically associated with the disease.
