Definition / general
  • Lungs are surrounded by visceral pleural, a delicate serous membrane arranged as a closed invaginated sac
  • Inner chest cavity is lined by parietal pleural membrane
  • Visceral and parietal pleura define the pleural space / cavity, which normally has minimal volume, unless lungs collapse or air / fluid collects between the two layers
  • Only minimal contact between right and left pleural sacs
  • Regional lymph nodes are internal mammary, intrathoracic, scalene and supraclavicular
