When body temp rises blood vessels in the skin do what?
When body temperature rises, blood vessels in the skin dilate. This expansion allows heat to be released from the superficial vessels of the skin.
If the blood vessels of the skin dilate the person appears?
When shock results from excessive dilation of blood vessels, the skin may be warm and flushed.
If a person becomes too warm what do blood vessels in the skin do?
Dilate.
What would be one effect of the dilation of the small blood vessels in the skin?
When blood vessels dilate so close to the skin, it would cause an outward appearance of flush on the skin. Blushing, for example.
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.

Why does the face reddens when blood vessels dilate?
Many small blood vessels in your face are close to the surface. When they dilate or expand, the result is increased blood flow which can cause the red appearance, especially if you have pale skin. Generally this redness goes away when the vessels return to their normal size and the blood flow is again reduced.
Why is blood attracted to heat?
Actually you have that backwards, blood is warmer than normal skin temperature. If the blood vessels in the skin dilate more blood will arrive at the skin making it hotter (and redder) than normal.
Why does your skin looked flushed while running and after for sometime?
More blood goes to your skin to create heat loss. This is where your blood vessels dilate (expand). This is called vasodilation.
What is the function of blood vessels and sweat glands in the skin?
Both the blood vessels and the sweat glands of the skin work to decrease body temperature when it is too high. The superficial blood vessels dilate to release more heat through the skin, and the sweat glands produce perspiration, which evaporates to reduce body temperature.
How do the heart and blood vessels maintain a stable body temperature in hot and cold?
During warmer weather, the blood vessels at the surface of the skin dilate. At the same time, our skin produces sweat, which evaporates - taking the excess heat into the atmosphere.
