Some Biophysical Modeling of the Human Circulation Apparatus

Abstract

Statistics from Hungary over the last seven years clearly show that diseases of the circulatory device lead the statistics on the causes of death. The Hungarian trend is the same as the global trend, with circulatory system disease being the most common cause of death in every country. The modeling of the blood volume, if we administer a certain substance amount, then its passing speed will depend on its concentration, hence the volume at which it spreads in the deposit. Consider the contraction and relaxation of the atrium/ventricle of the human heart; use the function of the rhythmic change for this. We apply the calorimetric principles for the measurement of the gastric blood flow. In the physio­pathology research of the circulation in arteriopathic people, when there are necessary arguments refering to the efficiency of new medicines or for the purpose of reestablishing the work capacity, the clinic diagnostic must be completed with laboratory samples: regional debt, peripheral arterial resistance, circulation time. Its measuring can be made with a normal double walls calorimeter and we measure the water temperature variations. Knowing the values of the previous formulas and the mass of blood circulated in that segment, we find out the segment’s flow. The human organism is a system because it is made up of a finite number of interacting p₁, p₂,… p_n elements, characterized by the quantitative degree of q₁, q₂,… q_n. The circulatory apparatus is a subsystem of the human body. In our opinion, the circulatory device should have a control associated with its own structure, which is likely to consist of neurons with hyperordonated spatial structure, called the “hypothetical secondary brain”, which performs certain control functions. This “hypothetical secondary brain” of the circulatory apparatus, in humans, functions continuously throughout their life.
