The visceral and parietal pleura are what keeps your thoracic cavity airtight. If the pressure gradient between the outside of your chest and the pleural space that your lungs occupy were compromised, via puncture wound or pneumothorax, then your lungs would crumple up like like a deflated balloon. The parenchyma (part of the lung you’re referring to) is spongy, but it won’t hold any air if it doesn’t have that pressure gradient to keep air in it. It takes very little to compromise that gradent. Two puncture wounds on each side of the chest would be enough
Yeah but a sponge in an airtight bag vs a sponge by itself will
But is isn’t like a normal sponge, it’s a sponge made of bags. If you puncture some part of it the other parts will stay dry

I assume they mean the GF is referring to puncturing the pleural lining to give the corpse a collapsed lung.
