Abstract. Presented results of the analysis of some characteristics of a living organism and a dead body in terms of thermodynamics. It is known that from the birth of a living organism entropy of the living body increases and at the moment of death reaches its maximum. After death remains a dead (physical) body, which is also characterized by its entropy. Based on this, the total entropy of any living organism can be represented as the sum of the entropies of a living body and a physical body. Since the living body is inherent in all signs of life, entropy of the living body can be called “entropy of the vital essence”. Thus, entropy of a living organism can be represented as the sum of the entropies of the vital essence and physical body. On this basis, the living organism is a thermodynamic system, built of two subsystems – the vital entity (VE) and the physical body (FB). In this case, FB after the death of a living organism can exist independently without the VE.
Thus, in terms of thermodynamics, a living organism has two separate components – the vital essence of the organism and the physical body. Since entropy characterizes the internal energy of the system and given that at least one of the components of the VE-FB system can exist independently, according to the laws of thermodynamics, the VE and FB can also be considered as separate thermodynamic systems, each of which can exist independently.
Like any physical body, a dead body is characterized by a certain internal energy. After death, the dead body of human and warm-blooded animals is cooled to ambient temperature. Thus, the total energy of the dead body can be represented as the sum of the associated energy of the dead body that remains in that body and the energy of the dead body that is released into the environment in the form of heat.
