How does blood pH vary across species? I can't find an article or chart listing this kind of information.
So far I've found bits and pieces like:
- Human blood pH is nominally 7.4.
- 7.4 seems to be a good value for dogs and cats (¿and probably all mammals?).
- For racehorses it seems to be roughly 7.4.
- Silkworm, Bombyx Mori, blood (hemolymph) has a pH of 6.45 (larval) and 6.57 (pupal).
- Bullfrog muscle(!) pH runs roughly 7 to 7.3. (Link to The Journal of Experimental Biology article, PDF) It's not clear if this is also blood pH.
But no real comparison.
Is there an authoritative comparison of blood pH between: mammals, reptiles, fish, invertebrates, etc.?
Is nominal/average pH at least constant across all mammals, or across all reptiles, etc.?
