It's the interstitial fluid of the plural membrane ... it increases during pluritis, some pneumonias, and tumors.

The organs protected by the rib cage include the heart, lungs, stomach, and liver.
Ribs: The ribs protect the lungs and expand as you inhale to facilitate space for the lungs to expand like the diaphragm. The ribs then contract expelling the air in the lungs. The ribs enclose the thoracic cavity providing bony protection for the vital organs of the thorax's heart and lungs.
The ribs protect your lungs (along with the sternum, which protects the heart).
Remember that superficial means closer to the skin and deep makes farther away (the core) from the skin. Therefore, the ribs are closer to the skin, so they are superficial to the lungs, and vice versa.

Hi all I no is there is the chest and lungs both have walls with fluid to stop them rubbing. I no this because when I went to doctors about pain in chest he told me I've managed to lose fluid between them causing me nasty pain and them rubbing. ( it was caused by nasty cough I had and I've got it again). Hope this answers abit of your question.
Heart
Intercostal musles are present between the ribs.
The inter coastal muscles in between the ribs make the ribs expand. the pleural membrane is like a slippery skin that sticks to the ribs and when they expand the lungs expand aswell.
the lungs are anterior to the ribs
the rib cage
The lungs and heart are protected and surrounded by the ribs called the rib cage.
the ribs make a cage that protects your heart and lungs.
Ribs have joints to protect our lungs.
I think it's your heart because its LHL (Lung, Heart, Lung) and then the ribs protect those organs.
