The morphological pattern of inflammation shown here is:
Serous inflammation is marked by the exudation of cell poor fluid into spaces created by injury to surface epithelia into body cavities lined by the peritoneum, pleura, or pericardium. Typically, the fluid in serous inflammation is not infected by destructive organisms and does not contain large numbers of leukocytes. In body cavities, the fluid may be derived from the plasma (as a result of increased vascular permeability) or from the secretions of mesothelial cells (as a result of local irritation); accumulation of fluid in these cavities is called an effusion.
