Modeling risk evolution of digestive tract functional violations when exposed to chemical environmental factors

Abstract

Modern methods of health risk assessment are based on the representation of individual and public health as a dynamic process of “evolution”, which describes a continuous course of negative (and positive) changes in the condition of the body. The article presents a conceptual diagram of multilevel health risk evolution modeling under the influence of environmental factors. The main aspects associated with the simulation of digestive processes in the “meso level” are considered. Some results of solving the problem of the flow in the digestive tract antroduodenal area taken into account tract motility. Further development ways of the model are outlines – account of biochemical reactions, secretory and absorptive functions tract. The proposed approach will enable not only to predict the risk of digestive system functional disorders, but also take into account basic physiological processes, mechanisms of income, distribution, excretion of chemicals.
