- Abnormal dilation of the medium bronchi occur - frequent obstructions occur in the airway damaging elastic fibers in bronchial wall - causes fibrous adhesion's which pull the wall of bronchus out. pooling of fluid occurs and is infected with pathogens - additional infection causes further damage and fibrosis to the lungs
excess fluid in the alveolar tissue may develop when....
- Inflammation is present in the lungs ( increased capilary permeability - plasma protein levels are low - pulmonary hypertension develops - blocked lymphatic drainage
