Which actions help the body conserve heat?
1) the hairs on your arms stand on end, which traps warm air close to your skin and basically insulates it - like thread in clothing. 2) vasoconstriction, where your blood vessels constrict, causing blood to flow closer to the centre of your body instead of closer to your skin, where heat would radiate out. 3) shivering - as your muscles contract, you warm up (kinetic to heat energy).
Can nuclear plants help conserve energy?
They can help conserve other fuels which are used to generate energy. They can be used in place of those fuels but they, along with all power plants, generate energy they do not conserve it.
What can I do to conserve energy loss on hot water pipes?
You can insulate the hot water pipes with spiral-wrap fiberglass insulation, foam tube insulation, or fiberglass pipe covers. These will all help reduce heat loss.
Does plastic help us conserve energy?
Not really, not unless the plastic is being recycled.
How does the body conserve heat?
It will try to generate heat by making the muscles move rapidly through shivering. Also your hair will raise hoping to trap heat between the body and the hair. But we have very thin body hair and that doesn't help but we see the effects of the tiny muscles pulling on the hairs to make them erect. This causes the skin to be pushed into a small hill. Something we call "goose bumps". Otherwise we have to use our brains to find a warm place.
Which mechanisms help the body conserve heat?
Shivering and vasoconstriction... B for plato users (:
How does vasoconstriction effect your body temperature?
Vasoconstriction (from "vaso-" meaning vessel) is constriction of the blood vessels. The opposite of vasoconstriction is vasodilatation, which is the relaxation of blood vessels. Vasoconstriction causes the radius of blood vessels to decrease, while vasodilatation increases radius.Blood flow through a vessel can be modeled as the flow of fluid through a pipe. Fluid flow through a pipe is directly proportional to the fourth power of pipe radius. As radius decreases, blood flow decreases, and vice versa. So vasoconstriction and vasodilatation can be used to regulate flow through a blood vessel.Peripheral blood vessels are usually considered those not in the core of the body and not those that supply skeletal muscles. A common example is the blood vessels of the skin. So peripheral vasoconstriction and vasodilatation control the amount of blood flow to the skin.Skin blood flow is a critical component of temperature regulation. To dissipate heat, warmblooded animals direct blood flow to the skin so it can be transferred to the surrounding environment. So if you were to exercise (which produces heat) or enter a steamy sauna, your skin blood vessels would vasodilate to direct that warm blood towards the skin surface so heat can be dissipated. Conversely, if you were to get cold for any reason, peripheral vasoconstriction would occur which would shunt blood away from the skin to help conserve heat and prevent its dissipation to the environment.
Body Fat and what help mammals to conserve body heat?
Hair and fur
What are used to help conserve heat in houses?
Loft insulation and double glazing.
How does vasoconstriction help warm the body up?
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.
How does vasoconstriction help warm your body up?
Vasoconstriction is the closing of arteries supplying blood to the bodies extremities. As the extremities are the coldest bits of the body, when the arteries constrict less heat is lost from the blood in these areas. This keeps the core of the body warm.
How do ovens conserve heat?
Ovens retain heat by utilizing insulation. The insulative coverings help prevent thermal conduction through the walls of the oven.
Do arctic foxes keep warm or cool?
They have smaller ears to conserve heat. Foxes from warmer areas have larger ears to help dissipate heat.
Do polar bears have large hairy ears?
No, they have smaller, but hairy, ears to help conserve heat.
Can you conserve heat released in a refrigerator?
As refrigerators give off heat from the back, the only real way to conserve the heat from it is to use it in a room that is already cold. Thus using the heat from the heat exchange on the back to add to any heat source in the room. This will not act as a heater for the room but may help to maintain the temperature very slightly when the heating is turned off.
