Vasodilator
Definition:
(a.) Causing dilation or relaxation of the blood vessels; as, the vasodilator nerves, stimulation of which causes dilation of the blood vessels to which they go. These nerves are also called vaso-inhibitory, and vasohypotonic nerves, since their stimulation causes relaxation and rest.
Example Sentences:
(1) With aging, the blood vessel wall becomes hyperreactive--presumably because of an augmented vasoconstrictor and a reduced vasodilator responsiveness.
