Question

Quizplus · Accepted Answer

The bends, also known as decompression sickness, occur when there is a rapid decrease in pressure, causing nitrogen that has dissolved in the bloodstream under high pressure to rapidly come out of solution and form bubbles in the blood and tissues. This can cause various symptoms ranging from joint pain and rashes to paralysis and death.
