Question: how does oxygen travel?


  1. @kitty123: Hmmm – do you mean in the body (oxygen transfer to/from the blood or cells?), in the air, or in water?

    I think (and I’m not chemist, so I’m sure Mick and DJ will be along to give you more details), in most situations (whether it’s in our bodies, in the air, or in water, it will transfer across from an area of high concentration into an area of lower concentration (so that both areas end up kind of the same concentration.


  2. Is Mia on the right track as far as answering this? That is, do you mean within an organism or where?
