Which gas is primarily responsible for causing the bends in deep sea divers who ascend too quickly?

  • AOxygen
  • BNitrogen
  • CCarbon dioxide
  • DHelium
Permalink
Correct Answer: Option B — Nitrogen
Explanation: Nitrogen dissolved in the bloodstream under high pressure can form bubbles if a diver ascends too quickly causing decompression sickness commonly known as the bends.
