In the opening paragraphs of his "Introduction to Comparative Biochemistry" Baldwin¹ stated: "In the body of the animal the properties of the perfusing fluid are kept remarkably constant. The total salinity, the p_H and the temperature remain constant within very small limits. A large part of physiology is concerned with the mechanism whereby this constancy is maintained."
