The U.S. Coast Guard said Thursday a remote operated vehicle (ROV) discovered a "debris field" near the Titanic wreckage site where a submersible went missing.
You can take this with a pinch of salt, but I believe that, based on your mention that the human body is mostly water, our bodies, down to our last cells, also have this internal pressure from the water in our bodies. The water is not compressible, but tissue is. And that would mean that not only our lungs will explode, but our entire cellular structures. It would be like squeezing oranges or lemons
But tissue is mostly water with some solutes and a lipid membrane. I don’t think the cellular structure would implode… It’s malleable enough… There are gelatinous animals in the deep sea with cells and such. But any cavity would implode. Lungs, thoracic cavity, digestive system, abdominal cavity, even the small pores in your bones if they aren’t packed full of equally dense liquid (not sure on this). The thoracic and abdominal cavity and pores in your bones are technically fluid filled… but since it’s not as densely packed as it would be under pressure at that depth, I think it would still get crushed. I think the difference between this and the cells is the rigidity of the structures. Cells can shrink decently well under pressure and then equilibrate via osmosis. Cavities and bones can not.

But this is just all me postulating.
