When body temperature drops below normal, dermal vessels are likely to constrict to maintain core body temperature, limiting heat loss through the skin. In contrast, when body temperature is elevated, the vessels in the dermis are likely to dilate to help the body release excess heat.
Dermal blood vessels constrict to conserve heat when body temperature drops below normal.
Body heat is released when dermal blood vessels relax and dilate.
No. Dermal vessels are likely to constrict in order to conserve central core heat. (I think.)
They vasoconstrict
True
When body temperature rises, the blood vessels in the skin dilate? This helps to decrease the temp of blood and thus decrease the body's core temp by having cooler blood circulating.

They get narrower therefore less blood flows through vessels. The body will try to keep the core warm. Doing so will cause the extremities to become less so.
The blood vessels dilate.
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.
The blood goes to all of the body parts.
When body temperature rises, blood vessels in the skin dilate. This expansion allows heat to be released from the superficial vessels of the skin.
Blood from the center of your body can be cooled by dilating superficial blood vessels. As the surface area of these vessels is increased, more heat can be released from the body, lowering blood temperature.
As temperature becomes colder, your blood vessels and muscles become smaller, not allowing as much blood to flow. You may notice that when you are cold, your dexterity is not as effective as it would be in warmer temperatures.
The temperature of the body decreasesThe blood pressure lowers with individual variations on the the systolic and diastolic measures. Also, the body temperature is modified. There is a difference between dilatation of large vessels like arteries and peripheral circulation which is constituted of small blood vessels or capillaries. (also in the brain)
blood vessels are the passageway of blood throughout the body
