The word root for dilation of an artery is "vaso-" or "vas-" as in vasodilation.
Vasodilation is a mechanism for thermoregulation . It is used for cooling down body temperature . Increased body temperature stimulates vasodilation .It results in increased blood flow to skin to aid heat dissipation .
When the arteroiles in the skin vasodialate the blood flow to the skin increases. One of the functions of blood is to transfer heat from the body to the environment to prevent it from overheating. So, if someone is getting warmer inside (like if you are exercising) then the arteroiles in the skin vasodialate allowing more heat to dissapate and keeping you cool.
This is called vasodilation. Vaso meaning vessel and dilation meaning getting wider.
Vaso-dilation (when your veins expand), increased blood pressure, increased heart rate.
This is called vasodilation. This is easy enough to remember: "vaso" means "blood vessel"; "dilation" means "to widen".
dilatation arterialis, commonly we mean vasodilation (or vaso dilatation)
If our body overheats, capillaries beneath the surface of the skin widen to allow more blood to flow through them. The blood carries heat energy, which can then leave the body when we sweat. Hence we cool down. If we are too cold, the capillaries narrow to reduce the volume of blood passing through. This reduces the amount of heat that is lost, and so we don't freeze to death as easily.

Your body can cool down when hot by sweating, which evaporates and provides a cooling effect. Your blood vessels may also widen to release heat through your skin. Additionally, seeking shade, applying cold water or ice packs to pulse points, and wearing light, breathable clothing can help regulate body temperature.
Vaso's population is 15,000.
Vaso Laskaraki was born in 1985.
