<Tr> <Th> FMA </Th> <Td> 9740 </Td> </Tr> <Tr> <Td_colspan="2"> Anatomical terminology (edit on Wikidata) </Td> </Tr> <P> In human anatomy, the pleural cavity is the thin fluid - filled space between the two pulmonary pleurae (visceral and parietal) of each lung . A pleura is a serous membrane which folds back onto itself to form a two - layered membranous pleural sac . The outer pleura (parietal pleura) is attached to the chest wall, but is separated from it by the endothoracic fascia . The inner pleura (visceral pleura) covers the lungs and adjoining structures, including blood vessels, bronchi and nerves . The pleural cavity can be viewed as a potential space because the two pleurae adhere to each other (through the thin film of serous liquid) under all normal conditions . </P> <P> In humans, there is no anatomical connection between the left and right pleural cavities . Therefore, in cases of pneumothorax, the other lung will still function normally unless there is a tension pneumothorax or simultaneous bilateral pneumothorax, which may collapse the contralateral parenchyma, blood vessels and bronchi . </P>

What is the name of the lining that immediately surrounds the lung
