Document Summary
Co2 has high solubility coefficient meaning that it takes less pressure to dissolve. Number of molecules are the same in the system but the pressures are different because k is higher so concentration is equal and that means pressure can be lower. N is so low that at atmospheric pressure we don"t drive any n2 into the blood (ex going underwater. Pressure is greater in depth so pressure gets high enough to drive n into your system. Problem arises when you come back up because as you come up driving pressure goes down and the n that is dissolved bubbles out and becomes gaseous. Worst part is in your joints: bubbles of joint bends. So come up slowly but that"s becayse solubility coefficient of n2 is high) Pressures are different in all the different systems. In alveolus pao2 is 100 but in atmosphere its 160. If not dissolved it does not have any pressure.
