basic homeostasis and negative feedback definitions

Homeostasis

Regulating conditions inside the body to maintain a stable internal environment in response to changes in both internal and external conditions

What can homeostasis regulate

Acidity akilinity hot cold water And glucose supply they fluctuate a little but only within certain bounds

What do automatic control systems do

They notice a change in optimal conditions send a signal to reverse change and then levels go back to normal

basic negative feedback layout

Receptors detect stimulus

Coordination systems interpret change and what needs to be done

Effector carry out response either muscle contracting or gland secreting hormones

Vaguely comparing endocrine system and central nervous system

Central nervous system- quick precise electrical impulses through nerves response is quick

Endocrine system- hormones travel around whole body through bloodstream only effect certain cells general effect is slower longer lasting and more generalised

Stimulus

Change in environment
