Energy loss and gain from your body need to be balanced so your body temp' stays at a Constant.
The extremeties of your body tend to be cooler than your core body. Energy is transferred from the Blood to the Tissues when it reaches the cooler parts.
Controlling body temperature requires...
- Temperature receptors in the skin to detect the external temperature.
- Temperature receptors in the brain to measure your blood temperature
- The brain which acts as a processing centre to recieve info from the Temperature receptors. Responding by triggering the effectors.
- Effectors (sweat glands and muscles) to carry out the automatic response
If your body temperature is too high, heat needs to be transfered to the environment. This is done by sweating, since evaporation from the skin requires heat energy from the body.
