Abstract: Digestion is the complex physiological process by which food that has entered the alimentary tract undergoes physical and chemical changes and the nutrients in it are absorbed into the blood and lymph. Starting from Bertalanffy’s systems theory, we wrote the differential equation systems of the digestive tract. We need to consider the digestive system as a so-called hierarchical system because it has many subsystems. The digestive system has a two-level control. Block diagrams can be used to examine the kind of goal orientation we want to make effective because this always depends on the current needs of the given organism. A block diagram of the brain-controlled digestive tract in case of normal functioning was recorded. A block diagram of the part directed by the hypothetical secondary brain was also recorded. We note that this part is functioning also under normal circumstances, only the brain activity obscures (masks) the everyday activity of the hypothetical brain.
