The process of increasing the lumen diameter of a blood vessel, especially an arteriole.
Widening of the blood vessels causing increased volume of flow in those vessels.
Relaxation of the vascular tree with the result of a fall in blood pressure.
Widening of blood vessels, especially arteries, usually due to certain nerve impulses or drugs that relax the musculature of the arteries.
The relaxing and widening (dilation) of blood vessels, which increases blood flow. Certain medications used to treat hypertension (high blood pressure) achieve their effect through vasodilation. As the blood vessels relax, they offer less resistance to the flow of blood, and blood pressure drops.
An increase in the diameter of blood vessels, which increases blood flow and lowers blood pressure.
The dilation of blood vessels results in enhanced blood circulation to a particular region of the body. In response to warm temperatures, vasodilation takes place under the skin, leading to greater heat dissipation from the body.
