Do peripheral blood vessels vasodilate to maintain a core body temperature?

If your body temperature gets too high, then one way that the body goes about lowering it, is to cause peripheral blood vessels to dilate, thus causing more blood to flow through these vessels, ie the vessels of the skin esp. This is why a light skinned person will appear flushed when they are very warm. Blood carries a lot of heat, so when blood rushes through these peripheral vessels near the skin surface, they will give up heat to the environment, thus cooling down the body. The reverse will happen in body temperature falls too much.

The pressure of massage techniques stimulates the release of these hormones to vasodilate the blood vessels?
histamine
What does peripheral blood vessels mean?
Peripheral means "at the edge". The blood vessels further away from the heart.
How does ear size help foxes maintain constant body temperature?
There are blood vessels in the ears that help maintain body temperature and the bigger the ear the more surface area it has to work with in order to regulate the temperature.
Peripheral vascular diseases are disorders of the blood vessels that are located outside of the heart and brain?
Peripheral vascular disease is disease of the blood vessels of the peripheries i.e. the limbs. Atherosclerosis, how ever is a generalised disease and other vessels are also involved
Blood vessels in the dermis aid in the regulation of?
Blood vessels in the dermis of the skin aid in the regulation of body temperature by constricting (vasoconstricting) to maintain internal body temperature, or expanding (vasodilation) to release heat and lower body temperature.
When the temperature increases. what does the brain do to try to maintain a constant temperature?
In hot weather the brain causers the vessels to move close to the surface and dilate. In cold weather it causes the vessels to move away from the surface and contract.
Contra indications for axillary temperature?
Skin disease. 2- Axillary operation. 3- Unconsciousness, shocked patients 4- Constricted peripheral blood vessels.
What is the large peripheral blood vessels into which extra-embryonic blood vessels open?
vitilline vein
What in tobacco constricts blood vessels?
Nicotine is the blood vessels' constrictor. Not all blood vessels, of course, but mainly the peripheral blood vessels, including the brain capillary blood vessels.
What structure in the dermis help maintain the temperature?
Firstly, your sweat pores help maintain temperature by opening or closing. When your body temperature is too high, the sweat pores open and more sweat is released outside of your body, thus resulting in more evaporation of sweat and a faster cooling of your body. When your body temperature is too low, your sweat pores close and sweat production decreases to minimize heat loss. Secondly, your skin arterioles and shunt vessels help maintain your body temperature by dilation or constriction. When your body temperature is too high, your shunt vessels constrict and your skin arterioles dilate, thus causing less blood to flow into the shunt vessels and more blood to flow into the blood vessels nearer your skin and losing heat more efficiently. When your body temperature is too low, your shunt vessels dilate and your skin arterioles constrict thus causing more blood to flow into the shunt vessels and less blood to flow into the blood vessels nearer your skin and thus minimizing heat loss. Hope that helps!
How do peripheral vasodilators work?
Peripheral vasodilators such as hydralazine (Apresoline), isoxuprine (Vasodilan), and minoxidil (Loniten) act by relaxing blood vessels.
Name two factors that increase peripheral resistance?
Peripheral resistance can be increased by an increase in blood volume and the constricting of blood vessels.
