Homostatis
  1. Homostatis is maintaining a stable internal enviroment
    1. Factors Include
      1. Temperature
        1. Water
          1. Blood Glucose (Sugars)
            1. osmoregluation
              1. ectasy wipes this from the brain
          2. Every cell needs water
            1. Every cell needs glucose for energy
            2. Warmth
              1. When its hot, we sweat
                1. Glands try to pump out the heat by sweat
                  1. Evaperation carries heat away
              2. Coldness
                1. When its cold, the erect gland contracts causing:
                  1. hairs to stand
                    1. goosebumps to form
                  2. Capillaries
                    1. Vasodilation
                      1. blood vessles get wider when hot
                        1. Evaperation from skin
                      2. Vasoconstriction
                        1. blood vesseles get thinner when cold
                          1. heat rises causing a thin layer of warm air above the skin
                      3. Hypeothaiamus
                        1. negative feedback acts to appose a change
                          1. normal - tempature increase or decrease detected - correct action - normal again
