Homeostasis is all about balancing inputs with outputs to maintain a constant internal environment.

The conditions inside your body need to be kept steady in order for your cells to function properly.

You have automatic control systems in your body that regulate your internal environment - these include both nervous and hormonal communication systems. All of you automatic control systems are made up of three main components. These work together to maintain a steady condition. These are:

  • receptors
  • processing centres
  • effectors

Your automatic control systems keep your internal environment stable using amechanism called negative feedback.

Thsi si when the level of something gets too high, or too low, your body uses negative feedback to bring it back to normal. This process happens wjthout you thinking about it - it's all automatic.

There is also a good, informative bit here: http://www.bbc.co.uk/schools/gcsebitesize/science/add_aqa_pre_2011/homeo/homeostasis1.shtml

Hope this has helped! :)
