Homeostasis is the maintenance of a internal environment.

Automatic control systems throughout the body maintain temperature and at steady levels, which are required for cells to function properly.

Strenuous and survival in hot or cold climates affect homeostasis. They affect temperature, blood levels, hydration and salt levels.

Two examples are scuba diving and .

Artificial systems, such as the temperature control system in an , are similar to body control systems.

Artificial and body systems have to detect stimuli, processing centres to receive information and responses and which produce the response automatically.

between the effector and the receptor of a control system reverses any changes to the systems steady state.

Some effectors work , which allows a more sensitive response. They work in directions.
