It is estimated that in a temperature beyond 35°C, a human body can no longer cool itself through ……………………………… . a. spurt b. squabble c. semblance d. perspiration

As perspiration ______, heat is removed from the body.

Normally the human body can endure a temperature of 105°F for only short periodsof time without permanent damage to the brain and other vital organs. What is thistemperature in degrees Celsius?

A body cools in 7 minutes from 60°C to 40°C. The temperature of the surrounding is 10°C. The temperature of the body after the next 7 minutes will be:

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
