Blood Flow ExamplesPoiseuille's law gives insight into the complex task of regulating blood flow to different parts of the body. In response to demand, the body must direct more oxygen and nutrients to one region of the body, and if necessary temporarily curtail the supply to a less essential region. Since the flow resistance depends upon the fourth power to the interior radius of a vessel, the processes of vasodilation and vasoconstriction offer powerful control mechanisms.
