Why there is negative pressure in pleural cavity?

Pleural pressure is negative (lower than alveolar pressure or barometric pressure) because of a "suction effect" caused by lung recoil. As the lungs recoil elastically, the inner and outer pleural membranes tend to be pulled apart but fluid within the pleural cavity keeps the inner and outer pleural membranes close together. This pulling force decreases the pressure between the inner and outer membranes lining the pleural cavity - an effect that can be appreciated by stacking several plastic cups together, submersing the stack in soapy water ensuring that the spaces between the cups fill with water, and then lift the stack of cups out of the water and try to pull the cups apart. A suction effect will occur producing negative pressure in fluid-filled spaces between the cups as you attempt to pull them apart. The fluid-filled space between the cups is like the fluid-filled space in the pleural cavity. That is why pleural pressure is negative.
