Blood vessels primarily receive innervation from the sympathetic nervous system, not the parasympathetic nervous system. The parasympathetic nervous system focuses on "rest and digest" activities, whereas the sympathetic nervous system is more involved in "fight or flight" responses, including the regulation of blood vessels' dilation and constriction.
