went over our unsure charts from yesterday.
the actual diagram had "change" in the middle, and going around in ilke a figure of 8, the top would be the opposite of the bottom.
eg. the top would go.. sense increase in heat -> sends message -> control centre at top -> thingy that does change -> change (negative feedback)
thats a crappy example coz i forget and i cbf getting my book behind me, but you get the point. the bottom would be for decrease in temp.
we compared an oven to a human. ovens have thermostats that detect overheat or underheat? haha and a switch that triggers it to warm up or stop.. this is like a human homeostasis system.
the thing is about these charts though.. is that they focus on only one change, and sensing ambient changes.. but not internal changes.
