DE MICHELI, Alfredo. The knowledge of animal respiration as a combustion phenomenon. Arch. Cardiol. Méx. [online]. 2014, vol.84, n.3, pp.224-228. ISSN 1665-1731.  https://doi.org/10.1016/j.acmx.2013.10.011.

The different stages leading to knowledge of the phenomenon of animal breathing are going from some writings in Corpus Hippocraticum to Aristoteles' and Galen's works, who considered the heart as the source of the animal heat. Later, Miguel Servet suggested that the inspired air can achieve other functions besides cooling the blood. After that, different explications of the animal heat were raised. About 1770, due to progress of knowledge in the chemistry field, first Mayow and later Black began to consider the animal respiration as a combustion. The important treatise Méthode de nomenclature chimique, published by Guyton de Morveau et al. in 1787 and soon after the Traité élémentaire de chimie de Lavoisier (1789) provided a solid support to Lavoisier's thought. This way on arrived to consider analogous the respiration and combustion phenomena. Studies on the animal respiration phenomenon continued in XIX century and in the following century it was possible to apply thermodynamic principles to biology: "generalized thermodynamics".
