At what temperature should the human body be maintained?Around 37°C Around 25°C Around 40°C Around 35°C 2Where in the body is your core temperature monitored and controlled?MusclesSkinSpinal cordThermoregulatory centre in the brain3What happens during vasoconstriction? The blood vessels that supply your skin capillaries become narrowerThe blood vessels move closer to the skin surfaceThe skin capillaries constrictThe blood vessels that supply your skin capillaries become wider4How do vasodilation and sweating help to reduce body temperature?By causing the muscles to contractBy increasing the transfer of energy in the form of heat from the skin to the environmentBy causing the body hairs to stand on endBy reducing the transfer of energy in the form of heat from the skin to the environment5Why do the hairs on our body stand on end when we are cold? To prevent vasodilationTo aid the evaporation of sweatTo prevent air trapping under themTo allow air to become trapped under them6How does shivering help to raise body temperature? It requires lots of respiration which generates heat It prevents sweatingIt causes vasoconstrictionIt causes vasodilation

How does vasodilation of dermal blood vessels help to decrease body temperature?Multiple choice question.The increase in blood flow to the skin increases heat production.It decreases blood flow to the skin, which keeps heat from dissipating into the environment.It increases blood flow to the skin, and heat dissipates through the skin into the environment.

Body temperatureMultiple Choicewill increase after blood vessels in the skin constrict.decreases when the rate of the chemical reactions increase.is lowered by shivering.results from the heat produced when muscles contract.is raised by sweating.

Name the process involved in the maintenance of constant body temperature that causes an decreased blood flow to the capillaries close to the surface of the skin by decreasing the diameter of the arterioles that supply them.

One response to increased internal body temperature is an increase in blood flow to the skin due to the ______ of dermal blood vessels.Multiple choice question.vasoconstrictionvasodilation
