Abstract: This paper deals witla blood flow caused by microvascular vasomotion with the focus on the effects of biood viscoelasticity on the pressure rise and wall resistance.It is shown that microvascular vasomotion plays a role of the "second heart" of the body which i.s of im portance in conveying blood, and that the effects of blood viscoelasticity greatly depend on the Weissenberg number and mean flow rate.-
