The article contains a description of mathematical models, the bases of which is the representation of the body circulatory system as a multifractal object. As examples, we consider the solution of two problems. The first issue is related to the normal state of the body’s life support system, namely, heat transfer in human skin. The model base is the equations of hydrodynamics and heat transfer. Quantitative results of calculating heat fluxes in three layers of the dermis are presented. The second issue deals with a violation of fractality due to the presence of arteriovenous malformation in the brain vascular system. The SolidWorks 2017 Flow Simulation software product serves as the basis for the implementation of a blood flow model in the presence of malformation. As a result of the simulation, data on the velocities and blood flow in the vessels were obtained for various cases of malformations.
