The usual concepts of homeostasis (actually the term rheostasis is more correct) are focused upon the mechanisms of circulation, respiration, digestion, excretion, mineral/water balance and bioenergetics. The nervous system and the hormone system are described as regulating, via feedback control, the various tissues in response to changes in the internal milieu of the body. Rheostasis is described as a function of the individual in response to its environment and role in the ecosystem.
A great deal is said about physiology (cellular, tissue and organ), some about seasonal variation (adaptations to climate changes and reproduction) and some about the nervous/hormonal control systems.
However, nothing is said about the underlying source for the generation of rheostasis in the body. It is my thesis that the source of the generation of homeostasis is the dynamic relationship between the result of evolutionary existent DNA expression according to changes in time of the energetic relationships of all the matter which comprises the physical body matrix and the response of the physical body matrix as an evolved system by/to fluctuations in the Solar System Interplanetary Electromagnetic Field Matrix (SSIEFM). Thus disruptions in physiology as disease is the result of disruptions in the physical body electromagnetic field matrix within the overall SSIEFM. Which means that altered physiology is the symptom and not the cause of disease.
Living systems as aggregations of matter have dynamically fluctuating electromagnetic fields that reflect the organization of the matter aggregation within the local space/time continuum.
The means which has evolved to perpetuate the particular material aggregations and control systems of living organisms is what Biologists refer to as Genetics. Gene expression is what enables the organism the maintain energy flow.
The genetic system of any organism has evolved to perpetuate the organism as a species and to maintain the organism within the environment it inhabits.
Gene expression then is the ultimate origin of homeostasis in all living systems.
Organic evolution through the ages has produced an amazing diversity of living organisms. Our interest is in the human primate with all its organ systems working in harmony. The scalar organization of the human body is as follows: quarks, nucleons and leptons, atoms and energy on the physical level; molecules, atomic bonds, moving electrons & protons, photons and energy dissipation on the chemical level; cells, tissues, organs, organ systems, the organism, populations, the ecosystem and energy concentration & flow through the organic systems at the biological level. Living systems have evolved with the ability to function within and deal with the particular requirements of the environment in which they are found in order to acquire, utilize and direct energy flow through the existent organism. The control systems for human homeostatic maintenance are likewise scalar. The physical and chemical scales are those of matter and the fundamental properties of matter. The biological scale with the human animal starts with the cell, the fundamental unit of life. All life comes from preexisting life. However, each cell has in the nucleus its genetic complement that is the result of organic evolution through many generations within the backdrop of the astronomical and geological evolution of the Earth. The human genetic code controls the development of the fertilized zygote to adult organism. This development takes place within this backdrop of the GMF and SSIEFM which influences the developing bioelectromagnetic fields of the embryo as well as the growth of cells into tissues, tissues into organs and organs into the organism as a whole.
Apart from cellular control by genetic expression, the means that the human animal genetic system has developed for overall integration of the organism are the nervous and hormonal systems. These two
