  • Homeostatis
    • The maintenance of a constant internal environment
    • Controlled internal environments
      • Body tempreature
        • Enzymes
          • work best at 37*
            • If the body is too hot or cold enzymes wont function properly
              • Could lead to death
        • Regulated by the brain
          • thermoregulatory centre
            • personal thermostat
            • contains tempreature sensitive receptors
              • monitor blood tempreature
            • Recieves impulses from the skin
              • gives information on skin tempreature
        • TOO HOT
          • hairs lie flat
          • sweat is produced
          • Blood vessels dilate
        • TOO COLD
          • Hairs stand up
          • You shiver
          • Blood vessels constrict
      • Water content
        • too much water could damage cells
      • Ion Content
        • Too much or little will damage cells
      • Blood sugar
        • needs to be maintained between certain limits
      • CO2
        • toxic in high quantities
