6 characteristics that define LIFE
-it is organized: there is definite structure
-it is made of cells: the units of life
-it metabolizes: set of carefully controlled complex chem rxns(eat, drink, sleep, defecate, exercise)
-responds to stimuli: this is quite variable
-it is homeostatic: attempts to maintain a constant internal environment
-it reproduces: there is a mechanism for continuity
-Ana: one’s self
-tomy: to cut

Study of how homeostasis is NOT maintained in an organism.
1) why do you have that disease? Where does it come from?
2) what is it?
-syndrome-don’t know what it is
-autoimmune—not an infection/disease but acts like one. Body attacks self.
3) how to treat it/how to survive it.
-maintenance of a constant internal enviro.
-from conception—> 16/18 years old, it is NOT maintained because everything is changing/growing/developing.
-at 21–>29 it is maintained, then it starts getting harder. As you age, the harder it gets.
-inhibits the deviation from the norm
-many homeostatic mechanisms are designed to stay at a “set point”. When it deviates, the negative feedback returns the level to “set point”.
