| regulators | (most invertebrates) internal composition is different from environment |
| homeostasis | maintenance of relatively constant extracellular conditions within the body in the face of fluctuating external conditions |
| enzymes | makes reactions go faster (works best at certain temperatures) |
| negative feedback loop | homeostasis (ex. temperature regulation system) a change in the variable being regulated brings about responses that move the variable in the opposite direction |
| positive feedback loop | homeostasis (ex. birth) acelerate a process leading to explosive system |
| sensor | monitors particular variable |
| integrator | compares signal to set point |
