The fluctuations in the body internal systems must be controlled within a narrow limits, for existence of living organism.The brain receives inputs from the receptors, and the outputs from the brain ensures the  homeostatic control.

The above examples are typical homeostatic responses by the organisms involved, because the inputs from the receptors  send signals to the brain ,and the organisms  responded to these with the example above.
