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.
