  • normal blood temperature (homeostasis)
    • decrease detected by receptors
      • Brain
        • vaso-constriction: sweat inhibited, piloerection (hair raises up), increased muscular activity, increase in metabolic rate
    • vaso-constriction: sweat inhibited, piloerection (hair raises up), increased muscular activity, increase in metabolic rate
    • vasodilation increases: blood flow, increased sweating, skin hair lowers, decrease in metabolic rate
  • Increase detected by receptors in skin
    • normal blood temperature (homeostasis)
      • decrease detected by receptors
        • Brain
        • vasodilation increases: blood flow, increased sweating, skin hair lowers, decrease in metabolic rate
    • Brain
      • Increase detected by receptors in skin
      • Normal body level of glucose
        • Excess in blood glucose
          • Detected by beta cells in the pancreas
            • Insulin secreted, Enzyme converts glucose to glycogen that is stored in the liver, increases glucose up take
              • Glucose level falls
                • Normal body level of glucose
                  • Excess in blood glucose
                    • Detected by beta cells in the pancreas
                      • Insulin secreted, Enzyme converts glucose to glycogen that is stored in the liver, increases glucose up take
                        • Glucose level falls
                    • Deficiency in blood glucose
                      • Detected by Alpha cells in the pancreas
                        • Glucagon secreted. Activates enzyme which turns glucogen to glucose
                          • Glucose level rises
            • Deficiency in blood glucose
              • Detected by Alpha cells in the pancreas
                • Glucagon secreted. Activates enzyme which turns glucogen to glucose
                  • Glucose level rises
