2. 
   Vasoconstriction
   a reduction in the diameter of small arteries (arterioles) which is caused by constriction of the smooth muscle fibres in the wall of the arteriole. Vasoconstriction is an important method of increasing the blood pressure. In local areas of damage it prevents blood loss by haemostasis. Local vasoconstriction can be caused by nerve impulses to the smooth muscle from the sympathetic nervous system, by locally released prostaglandins, serotonin and Epinephrine.

   Vasoconstriction
   A decrease in the diameter of a blood vessel (usually an arteriole) by contraction of circular involuntary muscle fibres in the walls, resulting in a reduction of blood flow to the area supplied by the vessel.

    Vasoconstriction
    `Vasoconstriction` is a narrowing of the lumen of blood vessels. It is the opposite of vasodilation. Factors causing vasoconstriction are called `vasoconstrictor`, also `vasopressors` or simply `pressors`. Vasoconstriction usually results in an increase of the blood pressure. (The opposite process, vasodilation, is the opening of blood vessels. ) Many vasoconstrictors also cause pupil dilation.
