How do the heart and blood vessels maintain a stable body temperature in hot and cold weather?
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.
What do blood vessels do when the weather is hot?
In hot weather - blood vessels dilate (widen) - to allow the exchange of heat between the blood and sweat glands. The sweat evaporates - cooling the blood.

When you are hot what do your vessels do to increase blood flow and reduce heat?
The blood vessels near the skin enlarge so that the hot blood is nearer the surface of the skin to transfer heat away from the body.
What causes your skin to turn pink when you are hot?
When you get hot, your blood flow increases and your blood vessels also get closer to the surface of your skin to allow the air to help you cool down. That is why your skin appears pink; your blood is closer to the surface.
When a person is overheated the skin becomes flushed and hot because?
the expanded blood vessels bring heat to the skin surface
How does your skin help keep your body cool?
when its hot, the sweat keeps you cool. tiny blood vessels near the surface of the skin help to cool your blood.
Which skin appendages aid in cooling the skin when the body temperature or the external environmental temperature is high?
RELAXING THE BLOOD VESSELS, SO INCREASE THE SURFACE AREA FOR THE BLOOD TO EXPOSE AND REDUCE THE HEAT EFFECT
How does the skin help in the regulation of temperature when it is hot?
On a warm day, vessels near the skin will undergo vasodilation in which blood vessels near the surface of skin will widen. This will cause the blood flow near the skin to increase and therefore transfer body heat to the environment, allowing the body to stay cool.
Why does your skin go red after a hot shower?
The body has a core temperature of about 98.6F for most people. If you are in a hot environment, or have just taken a nice hot shower/bath, your core body temp is going to be affected. To get rid of the heat, the superficial blood vessels, just under your skin, dilate to release the heat to the skin, sometimes in the form of perspiration with a little help from the eccrine (sweat) glands. When those blood vessels dilate so close to the surface of the skin, it causes the skin to become red, flushed or florrid.
