In large arteries, distributing blood to an area (hind leg of dog), the vasomotor substances (catecholamines) induce differences in flow. In case of state of vasoconstriction, the mean velocity of flow decreases, while the amplitude of pulsatile flow and the pressure increase. The radial expansion is wider. In case of state of dilatation, inverse reactions are observed.
