Within the general framework of the First Law one can make some ob- servations on the whole animal. The goal of the sum of all the metabolic processes in the living system is to maintain the internal energy, TL, and the enthalpy, JC, at constant values; that is, to maintain A °d = 0 = A JC de- spite the input of energy and the output of work. The attempt is \v made by the full-grown living thing to maintain a daily balance between the net energy taken in as food (q), and the work done (w). This work may be external physical work, or it may be internal work such as transport through the circulatory system, internal muscle movements of the heart and stomach, chemical transformations, etc. . ..
