Homeostasis
The maintenance of a constant internal environment in response to changes internally and externally
Organs of homeostasis
Brain, lungs, muscles, pancreas, skin, kidneys
Thermoregulation risks
Normal BT is 37C - optimum temp. for enzymes
Low BT - slower reactions, and hypothermia
High BT - enzymes denature, heat stroke, dehydration
How does thermoregulation occur?
Hypothalamus is thermoregulatory centre
Hypothalamus recieves information from skin receptor cells (ext temp) & internal receptor cells (int temp)
