-
Vasoconstriction is when blood vessels constrict (become narrower, smaller in cross-sectional area) by contracting the vascular smooth muscle in the vessel walls.
Vasoconstrictors are used to increase blood pressure or to reduce local blood flow.
-
Vasodilation is when blood vessels dilate (become wider) by relaxing the smooth muscle in the vessel walls.
