2.77b Thermoregulation

• The Negative feedback loop is a method of control and retaining constant conditions.
• The average body temperature of a human is 37/38 degrees centigrade. 
• The hypothalamus responds to a stimulus which is the temperature of the body or blood. 
• Body temperature feeds into the brain and is compared to the theoretical level of control.
• If the body temperature needs to be increased of decreased then it is brought about through the action of the effector such as the skin.
