Explanation / Answer

15. a.LINES THE UNDERSIDE OF THE CHEST WALL   [ Pleura has two layers, visceral pleura, the inner layer which stays in contact with the lung, and the parietal pleura which stay in touch with the chest wall]

16. a. COVERS THE SURFACE OF THE LUNG [ explained above]

17. b. COVERING AND LINING TISSUE   [ epithelial tissue are which stays in the outermost layer, means the cell layer which covers organs is called epithelial tissue of that organ ]

18. c. INTRAPLEURAL SPACE [ by definition the space between two layers of a bilayer membrane called intra not inter ]

19. a. BLOOD [ Haemo = haem = blood ]

20. c. AIR   [ Pneumo = air ]

21. d. CHYLOTHORAX [ Chylothorax mean the collection of lymphatic fluid inside intrapleural cavity]

22. a. ALWAYS NEGATIVE [ three reasons for intrapleural pressure, elastic recoiling of the chest wall and the elastic recoiling property of lung wall, both acts in opposite direction thereby creates a vacuum inside intrapleural cavity--. result in negative pressure relative to atmosphere, the third reason is surface tension of surfactant]

23. b. COLLAPSE [ This is due to the elastic recoiling of lung tissue, this tendency is prevented by surfactant and air inside the ling, residual volume and the opposite force of elastic recoiling of chest wall]
