explanations and information about: body temperature, vasodilation and vasoconstriction, heat stroke and hypothermia


body temperature

energy loss and energy gain from your body need to be balanced so that your body temperature remains constant.

the temperature of your bodys extremities tends to be cooler than your core body temperature. Energy is transferred from the blood to the tissues when it reaches the cooler parts.

controlling body temperature requires...

-temperature recptors in the skin to detect the external temperature.

-temperature receptors in the brain to measure the temperature in the blood.

-the brain which acts as a processing centre, to receive information from the temperature receptors, responding by triggering the effectors.

-effectors (sweat glands and muscles) to carry out the automatic response
