Abstract

The visceral and parietal pleurae are continuous with one another at the root of the lung, where the hilar airways and vessels enter the lung parenchyma, and are closely opposed to the individual pulmonary lobes, the inner aspect of the thoracic cage, and the lateral margin of the mediastina. The resultant pleura space contains scant fluid and is normally a potential space that becomes a true space only in disease states that cause accumulation of pleura fluid The visceral pleura is attached to the lung surface and is contiguous with the sub-pleura pulmonary interstitials. It is thick and apparently derives its blood supply from both pulmonary and systemic arteries, draining to the pulmonary veins. The visceral pleura individually invest pulmonary lobes.
