2.  homeo = same or unchanged › Greek homoio-, combining form of hómoios similar, like  stasis = to remain still or steady › Greek, from sta- base of histanai 'to stand‘ - a period or state of inactivity or equilibrium  involves a control system by which an animal maintains a stable internal environment, despite fluctuations in their environment.

3. To find out how homeostasis works:  To explore how and why the human animal maintains a stable internal environment,  including how a specific disruption results in responses within a control system to re- establish a stable internal environment

4.  the adaptive advantage for humans of their various homeostatic control systems  the biochemical and biophysical processes underpinning each mechanism › (e.g. equilibrium reactions, changes in membrane permeability, metabolic pathways).

5.  What happens when the control system breaks down completely due to extreme environmental factors? › ie when the control system cannot re-establish the homeostatic balance

6.  body temperature  blood pressure  osmotic balance  level of blood glucose  levels and balance of respiratory gases in tissues.

7.  What environmental factors might affect the homeostatic control system?  External influences such as: › exposure to extreme environmental conditions, › disease or infection, › drugs or toxins,  Internal influences such as: › genetic conditions or metabolic disorders

8.  purpose of the system  components of the system  mechanism of the system (how it responds to being disrupted within a normal range of environmental fluctuations)  possible effect of extreme disruption to the system by internal or external influences, resulting in its breakdown.
