Document Summary

Mercury is almost x2 as dense as iron. Can store o2 not only in blood but in tissues of its body. Pressure at bottom of the tech is 1100 atm (829 m of mercury) Anglerfish live down here aka black dragon fish. With increased pressure, have increased partial pressure of nitrogen. Nitrogen pressures increase with pressure as well as partial pressures of o2 and co2. At sea level pressures, theres 1 l of n dissolved in blood stream. Get more n dissolved in blood stream which compromised/inhibits signals through cns. Respond with hallucinations and euphoria the bends: If you"re going up, its a n related problem. Nitrogen starts to come out of solution as the pressure decreases. As they go to surface, pressure dropping around them. Like taking top off of soda, co2 bubbles out- this happened with n. N comes out of solution and gets trapped in joints and small muscles which is problematic.
