Answer Details
The increase in width of blood vessels in the mammalian skin at high temperatures is known as "vasodilation". This means that the blood vessels in the skin widen, allowing more blood to flow through them. This helps to increase blood flow to the skin, which can help to cool the body down in hot temperatures. As the blood flows closer to the surface of the skin, more heat can be lost through radiation and convection, which can help to regulate body temperature.
