Hemodynamics: (1) explores the flow features in the heart and blood vessels, in normal conditions and in pathologies; (2) studies the pressure—flow relationships and the transport of substances by blood; and (3) is a major factor in therapy optimization. Hemodynamics differ at the different length scales of the circulatory circuit. The blood circulation can indeed be decomposed into two major compartments: (1) microcirculation, at the cellular level, where the suspension of blood cell (strongly deformed or not) flows at low Reynolds number (Re); and (2) macrocirculation, in which blood can be supposed to be Newtonian in normal conditions and unsteadily flows at high Re.
