The skin dose not, but hairs raises, arteries shrink and you shiver in cold. But in hot the opposite happens hairs not raise, arteries expand and you sweat.< p>
Increased blood flow to the skin.
Regulate body temperature.
they have thick skin
skin provides a control mechanism to maintain a homeostasis temperature of the whole body. when body temperature too low the body generates a body shaking mechanical force to provide energy to the body. when body temperature too high, the sweat gland releases energy as heat form to reduce body temperature.
During exercise, the increased muscle activity increases body temperature. The skin responds to the need to bring body temperature back into normal range in two ways. The blood vessels near the surface of the skin dilate to release extra heat, and the sweat glands make perspiration, which evaporates to lower body temperature.
yes
To cool the surface of the skin and reduce body temperature.
Yes, reduced blood flow to the skin raises body temperature. The skin provides a way for excess heat to exit, and so increased blood flow to the skin increases heat loss and decreases body temperature.
by sweating
Body temperature regulation
Vasodilation is a mechanism for thermoregulation . It is used for cooling down body temperature . Increased body temperature stimulates vasodilation .It results in increased blood flow to skin to aid heat dissipation .
Human growth hormone (hGH) is a hormone that is naturally produced by the body. Effects of growth hormones are decreased body fat, increased muscle mass, increased bone density, increased energy levels, improved skin tone and texture, increased sexual function, and improved immune system function.
