DISEASES OF THE LUNGS.
Divisions of lung diseases. Bronchitis, pneumonia, pleurisy, their results, nervous disorders, asthma, hiccough. Œdema. Emphysema. Morbid growths, neoplasms. Infectious and parasitic diseases.
Inflammatory diseases of the respiratory organs situated within the chest may be divided into: inflammation of the air tubes within the substance of the lungs—bronchitis:—inflammation of the spongy tissue of the lung—pneumonia:—inflammation of the covering of the lungs and lining serous membrane of the chest—pleurisy:—and complicated cases in which two or more of these conditions coexist. Beside inflammatory diseases there are the various permanent morbid results of these affections, such as consolidation of lung from exuded products becoming organized; collapse (compression) of lung from organization and contraction of false membranes, thickening or dilatation of bronchial tubes as a result of bronchitis; also nervous affections, such as asthma and hiccough; morbid alterations in the lung tissue independently of inflammation, as pulmonary or pleural œdema and emphysema; specific morbid deposits, as tubercles, glander nodes, cancer, melanosis, etc., and morbid states, due to parasites, as in the verminous affections of cattle, sheep, etc.
