It's the interstitial fluid of the plural membrane ... it increases during pluritis, some pneumonias, and tumors.
the flesh and padding muscles in between each
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.
Intercostal Drainage is a medical procedure where a hollow tube is inserted between the ribs, into the chest i.e. in pleura ( covering of lungs ) to drain the unwanted collection in the chest - air, pus, blood or fluid.
The ribs protect your lungs (along with the sternum, which protects the heart).
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.

Lungs
