Blood vessels widen and narrow due to body temperature conditions. for example, if the body is too hot the blood vessels will widen to bring more blood closer to the outer layer of the skin to release some heat. (this is why your face gets red when working out) when the body is too cold the blood vessels will narrow to prevent heat loss by the blood and face becomes more pale.
Core body temperature is the balance between energy produced in the body and heat loss from the body. The dilation of blood vessels in the skin helps increase the loss heat from the body core to the skin and from there out of the body. Of course if one lived in a climate much warmer than 37 degrees the effect would be reversed.

Which layer of the skin has blood vessels?
The layer of the skin that contains blood vessels is the dermis. Blood vessels in the dermis help nourish the skin cells and regulate body temperature.
What is the arculatory system?
The circulatory system is the body's network of blood vessels, including arteries, veins, and capillaries, that transports blood and nutrients throughout the body. It also helps regulate body temperature and remove waste products. The heart is the key organ in the circulatory system, pumping blood through these vessels.
How does the skin help to regulate body temperature 2 examples?
The skin helps to regulate body temperature through the process of vasodilation and vasoconstriction. When the body is too hot, blood vessels near the surface of the skin dilate, allowing more blood to flow to the surface and release heat through sweating. When the body is too cold, blood vessels constrict to reduce blood flow to the surface, conserving heat in the body's core.
Blood vessels help regulate your body's temperature when it's hot your blood vessels do what to increase blood flow and release heat?
Blood vessels dialate (open more) and the heart rate increases to dissipate body heat. In cold temps such as hypothermia, the blood vessels constrict and the heart rate lowers. Extremehypothermia or hyperthermia are both life-threatening.
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.
What is the circulatory system transport this which helps regulate temperature?
Your question is not quite clear, but if you are asking "does the circulatory system help maintain body temperature?" then I would the answer is yes. It moves blood throughout the body which regulates the body temperature. Doing so also supplies supplies oxygen and nutrients for the cells in your body.
What structure allows skin to receive nutrients eliminate waste and helps regulate body temperature?
Blood vessels, good luck on the rest of the test!
Which structures help maintain your body temperature?
Structures such as sweat glands, blood vessels, and the hypothalamus in the brain help regulate body temperature. Sweat glands release sweat to cool the body through evaporation, blood vessels dilate to release heat, and the hypothalamus controls these processes to maintain a stable body temperature.
What is distributed througout dermal papillae?
Blood vessels are distributed throughout dermal papillae in the dermis layer of the skin. These blood vessels help to supply nutrients and oxygen to the epidermis and hair follicles, as well as regulate body temperature through blood circulation.
How can blood keep your body temperature stable?
Blood helps regulate body temperature by transferring heat produced by metabolism to the skin, where it can be released. When the body temperature is too high, blood vessels dilate to release heat, and when it is too low, blood vessels constrict to retain heat. This process helps maintain a stable internal temperature for proper bodily functions.
What is the role of the human in temperature regulation?
Several mechanisms regulate body temperature. Vasoconstriction of blood vessels at the skin surface occurs when temperatures fall, and vasodilation of blood vessels occurs when temperatures rise. Norepinephrine , thyroxine and epinephrine are secreted when to increase the metabolic rate when temperatures drop.
When body temperature rises blood vessels in the skin what?
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.
