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.

va·so·di·la·tion

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

vasodilatation

/vaso·di·la·ta·tion/ (-dĭ″lah-ta´shun) vasodilation.

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.

vasodilatation

Widening of blood vessels as a result of relaxation of the muscles in the walls. This allows a greater volume of blood to pass through in a given time. Compare VASOCONSTRICTION.

vasodilatation

widening of the lumen of a blood vessel, due to relaxation of the smooth muscle in its wall, mediated by neural (autonomic) control, local or blood-borne chemical factors, or rise in temperature. Syn vasodilation.

vasodilatation, vasodilation

a state of increased caliber of blood vessels.
