cold weather causes vasoconstriction. Vasoconstriction restricts blood flow near the skin, so less heat is lost through the skin.

What are three hormones that produce vasoconstriction?
norepinephrine, epinephrine and angiotensin II
What is the importance of negative feedback in the control of vasodilation and vasoconstriction?
Vasoconstriction and Vasodilation are a part of a body negative feedback, in which the body tries to restore homeostasis. Homeostatis is the function of keeping the internal body at it's general temperature (37 degrees Celsius). Without the negative feedback of Vasoconstriction and Vasodilation, the body would either be at a very low or very high temperature and this high/low temperature could cause death.
Why does vasodilation and vasoconstriction happen in a cycle?
Vasodilation and vasoconstriction occur in a cycle to regulate blood flow and maintain homeostasis in the body. Vasodilation refers to the widening of blood vessels, which allows for increased blood flow and delivery of oxygen and nutrients to tissues. Vasoconstriction, on the other hand, is the narrowing of blood vessels, which reduces blood flow and conserves heat and nutrients. These processes are dynamically regulated based on various factors such as tissue oxygen levels, metabolic demands, and body temperature.
How do the humans effects the ozone?
Humans produce CFC's. These CFC's react with ozone to deplete it.
How humans are the cause of ice caps melting?
Humans produce greenhouse gases when they drive their cars or plants manufacture products. These gases are trapped in the atmosphere and allow solar radiation(the Sun) in to the earth atmosphere but doesn't let it out. The excess heat that is trapped increases the temperature which cases the ice caps to melt; even a small rise in temperature causes mass melting.
Is body temperature elevated or decreased with vasoconstriction?
the temperature is elavated by 67%

How would you explain what vasoconstriction mean?
Vasoconstriction is the narrowing of blood vessels.
What role does vasoconstriction play in haemostasis?
Vasoconstriction helps limit blood loss from a ruptured blood vessel, buying precious time for platelets and coagulation to form. Vasoconstriction is instantaneous but short-lived and platelets and coagulation are needed for a lasting effect.
When attempting to lower a person's body temperature in response to hyperthermia one should avoid treatments that induce shivering or vasoconstriction?
Shivering produces heat and vasoconstriction reduces the ability of blood to dump its heat load to the skin's surface where cooling occurs.

What are the two processes in a cycle pattern rather than vasoconstriction happening?
vasoconstriction and vasolidation
How much saliva do humans produce in a lifetime?
Humans produce about 40,000 litres of saliva in a lifetime.
What is vasoconstriction?
Vasoconstriction is the constriction or narrowing of blood vessels by small muscles in their walls, slowing or blocking blood flow. Vasoconstriction is the constriction of blood vessels that increases blood pressure.
What is the medical term meaning constriction of blood vessels?
Vasoconstriction is the normal narrowing of a blood vessel.
