I know how the body works, at least regarding red blood cells, should have been obvious from my previous post.
So no: there is no noticeable carbon acid in my body, there migt be traces in the cells itself. As soon es it touches blood, the red blood cells pick it up, more prcisely: the dissolved CO2 is forcing the hamoglobin in the red blood cells to release the O2 in exchange for the CO2.
Actually you learn stuff like this in school
So no need to try to teach us with your half assed half wrong ideas how you think it works.
