vasodilating
Opening blood vessels
Vasodilating means causing blood vessels to widen or relax.
The term appears in medical contexts describing drugs, substances, or physiological responses that increase blood flow by expanding arteries and veins: Nitric oxide has a vasodilating effect on coronary arteries.
Exercise and certain medications are vasodilating; cold and stress are vasoconstricting.
