Homeostasis of a physiological system is maintained by a functional metabolism and by a metabolism cotrol function of living body. The oxygen distribution system which is necessary for life is a good example of homeostasis. The distribution of blood depends upon the metabolism and also upon the quantity of oxygen used by the organism. It is believed that better diagnoses of health disorders can be made using system engineering methods to study homeostasis and to make the blood distributing function clear through the understanding of metabolism state information. Proper spatial orientations are necessary for effective oxygen distribution in the organism according to changes of metabolism. The purpose of this report is to make clear the fact that metabolic receptors exist in the body. These sensors (metabolic receptors) produce depolarization or hyperpolarization of receptor according to the supply and demand of oxygen. When the receptor depolarizes, local currents flow and generator potentials are produced in the nerve endings. As the receptive cell has an electromotive pump, it hyperpolarizes itself if sufficient oxygen is supplied by the blood stream, and thus decreasing the sensitivity of the nerve endings. The fact that an obstruction in aerobic metabolism produces depolarization indicates that this is highly dependent on oxygen. Experimental results on thermal stimulation, temporary cessation of respiration, electrical stimulation, and electromotive potential phenomena are reported and reference is made to the fact that blood flow regulation is largely dependent upon the metabolism state information system.
