Definition

The pleural cavity exists between the mesothelial lined visceral and parietal pleurae. This cavity is filled with a small amount of fluid, termed pleural fluid, which functions to reduce the friction between the pleural membranes during the respiratory cycle. Pleural fluid is a plasma filtrate from the capillaries of the parietal pleurae whose production is dependent on three factors: plasma oncotic pressure, capillary permeability, and capillary hydrostatic pressure. The removal of pleural fluid is through lymphatic and venule reabsorption via the visceral pleurae. It is this balance of production and reabsorption that maintains a physiologically normal level of pleural fluid, 0.26 mL/kg body weight. When a pathological process modifies this balance through increased fluid production and/or decreased reabsorption, the resulting accumulation of fluid is termed a serous effusion.
