| ==Overview==
| |
| '''Acid-base [[physiology]]''' is the study of the [[acids]], [[Base (chemistry)|bases]] and their reactions in the body. For survival, acid base [[homeostasis]] is an absolute requirement.
| |
| | |
| The traditional approach to the study of acid-base physiology has been the [[empiric]] approach. The main variants are the [[base excess]] approach and the [[bicarbonate]] approach. The modern [[quantitative]] approach introduced by [[Peter A Stewart]] in 1978<ref>{{cite journal |author=Stewart P |title=Independent and dependent variables of acid-base control |journal=Respir Physiol |volume=33 |issue=1 |pages=9-26 |year=1978 |pmid=27857}}</ref> is now emerging as the most correct approach.

| ==pH parturition== <!--pH parturition redirects here-->
| |
| [[pH]] parturition is the tendency for [[acid]]s to accumulate in basic [[fluid compartment]]s, and [[chemical base|bases]] to accumulate in acidic compartments.
| |
| | |
| The reason is that acids become negatively [[electric charge]]d in basic fluids, since they donate a [[proton]]. On the other hand, bases become positively electric charged in acid fluids, since they receive a proton.
| |
| | |
| Since electric charge decrease the [[membrane permeability]] of substances, once an acid enters a basic fluid and becomes electrically charged, then it cannot escape that compartment with ease and therefore accumulates, and vice versa with bases.
