No the inside of the sub is pressurized

With my six years of experience in US submarines, I can tell you this... my ears didn't popped like being on a airplane, when the hatches were closed and we proceded out to sea! Sure, they popped when I was in the torpedo room and a really fat guy came through the water-tight door but then he sealed it off and no air could get out!
The bends is caused by breathing compressed air. The earth's atmosphere contains approximately 80% nitrogen and it is that nitrogen, when under pressure, that gets into your bloodstream when diving. Open water, sport divers follow down time protocol that limits the depth and time the diver stays down such that he/she can surface immediately and not suffer the bends. The bends being nitrogen gas depressurizing and trying to come out of the diver's body.
The submarine's atmosphere is NOT pressurized. It is maintained at normal surface pressure. The hull does contract with water pressure and may account for slight changes in internal pressure but is compensated for. Without the pressure, the nitrogen in our air stays at the same volume which is too large to be absorbed in our bloodstream.
So, the answer to your question is NO, submariners cannot suffer the bends if the sub surfaces too quickly.

What happens with the bends is that the further down a scuba diver goes the freater the pressure on him, this means the bubbles of Nitrogen in his blood are compressed, and then, if he rises really quickly these bubbles expand rapidly and so you get huge bubbles of Nitrogen in your blood and these can kill you if they get to your brain, paralyse you if they get to your Spinal cord and cause lots of pain whereever they are
This doesn't happen to a Submarine crew because they have a constant pressure maintained inside the Sub therefore the Nitrogen cant compress and expand so it cant give them the huge Nitrogen bubbles that are the bends

No it is pressurised.
Also divers need to be at pressure for some time to saturate their blood with gases.
If a submarine sank and they had to escape they have a system that allows them to leave the submarine and make a free ascent. As they rise the pressure decreases so the air in the lungs expands so they blow out all the way up. As they have not spent any real time under pressure they should be fine.

No the pressure in the sub remains constant no matter how deep it dives whereas the pressure on a scuba diver grows greater with depth. This forces nitrogen from his air into his blood, which must be dissapated slowly by rising slowly to the surface. If not done the nitrogen will come out of solution and "fizz" in your blood like a soda can suddenly opened. This can cause extreme pain, paralysis or even death.

The close residing circumstances may not in any respect let a co-ed sub team. There are not adequate slumbering quarters for the team through the indisputable fact that is, now to not teach adequate to allow females and men serving alongside with one yet another. As for an all-woman team, it changed into tried in the Eighteen Eighties, i imagine. the difficulty is, because that women human beings are not allowed on subs now, you may be cobbling together a team of sailors who've not in any respect executed some thing remotely like journey. to boot, that is medical undeniable actuality that females those who co-habitate synchronize their sessions. one hundred and fifty+ women human beings on the rag and left in a submerged tube thousands of ft decrease than and thousands of miles faraway from their next bottle of midol, and then you provide them nukes? and also you difficulty about Iran doing some thing loopy!

no it doesnt.as bends r created due to sudden difference in the outside presure.which causes the disolved oxygen in the blood to get released this causes the bends.however the subs are maintained at the atmospheric presure so it doesnot cause any changes to the ouside presure

no because the submarine is pressurized - like an airplane cabin.

If they are unside the sub as it surfaces, then no, because inside it is pressurized, but if they are outside they will.

No, the pressure in the sub remains constant.
