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.
Why do two processes happen in a cycle pattern instead of vasoconstriction only?
Vasoconstriction is trying to make you warm, but Vasodilation tries to cool you down. These two happen in a cycle pattern so that not all your blood is going to your skin or away from the skin. Vasodilation will be making you sweat, use the toliet and produce saliva more while Vasoconstriction will be contracting your muscles to make the hairs on your arms and legs stand up on end also producing goose bumps to try to warm you up.
Which body systems interact when a person shivers to warm up?
The circulatory system undergoes vasoconstriction -- a process where blood vessels constrict in order to reserve heat in the core of the human body. The muscular system is responsible for shivering. Rapid twitching of the muscle results in heat being produced.

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).
Explain the term Vasodilation and Vasoconstriction. how do these process contribute in temperature-regulationof the body?
Vasodilation refers to the widening of blood vessels, increasing blood flow and heat loss through the skin, which helps to cool down the body during hot conditions. Vasoconstriction, on the other hand, is the narrowing of blood vessels, reducing blood flow and heat loss through the skin, which helps to retain heat and warm up the body during cold conditions. These processes play a crucial role in temperature regulation by adjusting blood flow to the skin to maintain a stable core body temperature.
