vasodilation

 [vas″o-di-la´shun]
1. increase in the caliber of blood vessels.
2. a state of increased caliber of blood vessels. Extreme, abnormal vasodilation is called angiectasis. adj., adj vasodi´lative.

(vā'sō-dī-lā'shŭn, vas-ō-),
Widening of the lumen of blood vessels.
Synonym(s): vasodilatation

vasodilation

(vā′zō-dī-lā′shən, -dĭ-) also

vasodilatation

(-dĭl′ə-tā′shən, -dī′lə-)
n.
Dilation of a blood vessel, as by the action of a nerve or drug.

vasodilation

[-dīlā′shən]
Etymology: L, vas + dilatare
an increase in the diameter of a blood vessel. It is caused by a relaxation of the smooth muscles in the vessel wall. Also called vasodilatation. Compare vasoconstriction.

va·so·di·la·tion

(vā'sō-dī-lā'shŭn)
Increase in the caliber of a blood vessel due to relaxation of smooth muscle fibers in the tunica media. This increases blood flow but decreases systemic vascular resistance.
Synonym(s): vasodilatation.

See VASODILATATION.

vasodilation

the expansion of blood vessels by relocation of muscles mainly controlled by the sympathetic nervous system (see AUTONOMIC NERVOUS SYSTEM).

Vasodilation

The increase in the internal diameter of a blood vessel that results from relaxation of smooth muscle within the wall of the vessel thus causing an increase in blood flow.

vasodilation (vāˈ·zō·dī·lāˑ·shn),

n state of dilation or widening of a blood vessel.

va·so·di·la·tion

(vā'sō-dī-lā'shŭn)
