The integumentary system regulates temperature inside the body by insulation, trapping heat inside the body and making it difficult to escape. This is one of the reasons why the human body is normally warm to the touch.
Part of the heat liberating apparatus of the body is the eccrine sweat gland. Eccrine sweat glands are found in the skin, mostly on the palms of the hands and the soles of the feet.
Sweat glands aid in cooling the skin by producing sweat, which evaporates and helps dissipate heat. Arrector pili muscles contract to help release heat by causing hairs to stand up, allowing for better air circulation over the skin.
The primary excretory organ that helps regulate body heat is the skin. Through processes like sweating, the skin releases heat from the body to cool it down. Sweat glands in the skin produce sweat, which evaporates from the skin's surface, taking heat with it and helping to maintain the body's temperature.
Perspiration is moisture on the skin which evaporates. Evaporation sends the atoms of perspiration into the air. It takes energy (heat) to do this, so as the heat leaves the skin, the skin becomes cooler.
It helps keep out foreign bodies.
The skin keeps it in.
Skin is the largest organ of the human body. It is a protective covering - keeps bacteria out, keeps warmth in. It provides us sensory perception: we feel through nerve endings on the skin (touch, heat, cold, pressure, pain). Skin acts as part of the excretory system by ridding the body of salts (sweat). It helps us produce vitamin D when we are exposed to sunlight.
I think it might be the fatty layer. -JoshuaP
no,cold wated keeps your skin refreshed its keeps your skin from getting dry
Vasoconstriction keeps you warm by making the blood vessels of the skin smaller thereby not allowing as much blood to flow to the skin. This reduces the amount of heat that is lost through the skin.
Hair and eccrine sweat glands
Yes, they do. It feels comfortable and nice. Just because they have fur that keeps them warm, doesn't mean when they go on a warm platform, they get too hot! Animals with fur can sometimes withstand more heat than we can. The fur on them not only keeps them warm, but because it is so thick, the fur takes the heat and hasn't reached the skin part yet. (You see, there is the outer side of the fur, and the inner side of the fur, which is attached to the skin.) If heat touches the outer side, the animal can't feel that much heat because it hasn't reached the skin. For example, you touch a hot surface with your skin. If you put a thick, fur coat above the surface then touch it, it doesn't hurt. It works too if you have it all over your body.
Most heat exits the head, most of the rest is through water sweated through the skin.
Steam burns are painful because they damage the skin just like any other burn. Steam burns hurt because the water in steam keeps the heat trapped in the skin.
they have black skin which absorbs the little of the sun's heat and it keeps them warm. I hope this was what you were asking.
Moisture
It is not the fur that insulates the polar bear. The polar bear's skin is black, so it absorbs heat and keeps heat inside the body. The white fur is merely for camouflage.
