Abstract

The internal environment for maintaining life in the human body is supported by a particular control mechanism. The function of this internal environmental control mechanism is to transport organic materials and oxygen in a timely fashion according to the environment state information of the individual, to maintain the condition to acquire free energy. The fluid environment in the tissue is governed mostly by the oxygen state variable related to the adjustment of oxygen pressure of the tissue and the effective density of the substrate and electrolytes. While the human body is always in contact with the external environment, an adequate adjustment of the internal environment of the human body will be impossible without the state information. The internal environment near the body wall is separated from the external environment by the epithelial cell layer. The sodium ion density difference between the inside and the outside of the epithelial cell layer is maintained by the sodium pumping action of the epithelial cell. The electromotive pump of the epithelial cell and the sodium ion charge distribution of the tissue fluid are closely related to the oxygen state variable of the tissue. This paper discusses the measurement of the dynamical change of the state of the internal ions and the dynamical change of hemoglobin, produced by the modification of the internal environment, and the biomag-netic phenomenon caused by the epithelial current (called receptor magnetic phenomenon). By discussing their relations, the function and the control of the internal environment state information receptor of the living body are investigated.
