The more the viscosity, the higher the resistance. The viscosity in turn, mainly depends on the hematocrit. The longer the vessel, the higher the resistance. And the "narrower" the vessel, the higher the resistance. As the vessels get narrower, the fastest-flowing streams of blood at the center are lost. So resistance is related to the fourth power of radius. In serially arranged vessels resistance is added up. And in parallelly arranged vessels the resistance decreases.
