Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Blood vessels in the skin will ____ to help release excess heat
A
dilate
B
constrict
C
move
D
release blood
Explanation: 

Detailed explanation-1: -Blood vessels leading to the skin capillaries become wider-they dilate-allowing more blood to flow through the skin and more heat to be lost to the environment. This is called vasodilation .

Detailed explanation-2: -The blood vessels in the skin expand and dilate which releases heat or holds heat in. As they expand, blood flow increases and heat is released to our skin which holds about 3 million sweat glands.

Detailed explanation-3: -Regulation of body temperature: The skin has a large surface area that is highly vascularized, which allows it to conserve and release heat through vasoconstriction and vasodilation, respectively. When body temperatures rise, blood vessels dilate to increase blood flow and maximize the dissipation of heat.
