Scientific problems considered in this paper presenting the achievements are mainly focused on comparisons of tribological processes, which occur during flow of biological fluids around joint cartilage cells during lubrication of human joint surfaces as well as surfaces of micro- and nano-bearings used in micro-mechanisms. The tissue growth presented in this paper is the process of change of mass of a biological system defined by genetic (congenital) factors and dependent on epigenetic (environmental) factors (temperature, mechanical stress and strain, internal and external physical fields, etc.). This paper shows effects of influence of congenial growth and genetic code of bio-bearing or bio-joints material on the lubricant viscosity and lubricant process. In living tissues there is a growth strain defined by genetic code and depending on many other factors (such as temperature, force factors, chemical substances, etc.). A general theory of materials with memory is the theory of simple fluid developed by Noll and Koleman. The simple fluid theory described in this paper is based on the assumption that stress is defined by a whole deformation history.
