Comprehensive mathematical model of microcirculatory dynamics(II) - Calculation and the results

The mathematical model described in Part I was solved using " influence lin e method" combining analytical method and finite element method. Many impor tant aspects of microcirculatory dynamics were analyzed and discussed. It s how that interstitial fluid pressure changes its sign twice within one arte riolar vasomotion period and it is therefore not important that interstitia l fluid pressure is a little higher or lower than atmospheric pressure; art eriolar vasomotion can periodically result in lymph formation and interstit ial total pressure plays an important role in this procedure; local regulat ion of microcirculation can meet metabolic need some extent in the form of dynamic equilibrium. The property of arteriole as a " resistant vessel" and the efficiency of microvascular network as heat exchanger are also shown. These results shaw that the comprehensive mathematical model developed in P art I is physiologically reasonable.
