Document Summary

Ph is referring to the amount of h+ in any given solution. 7 is neutral, anything above that is alkaline (basic) and below is acidic. Normal range for arterial ph is 7. 35-7. 45. Ph depends upon [hco3-] in your kidneys and pco2 from your lungs when you breathe. There is always going to be a ratio of bicarbonate and carbonic acid. H2o + co3 h2co3 h+ + hco3- memorize this equation. If you slowed breathing down and retained more carbon dioxide then the bicarbonate would go up in order to retain then ph. This is the purpose of bicarbonate, to always keep ph within a certain range. Your kidneys are filtering your blood, bicarbonate is in your blood and you"re going to lose it unless your kidneys can get it back. The kidneys take buffered acids and produce more bicarbonate on a regular basis.
