Step-by-step explanation:

Homeostasis is the ability or quality of the body to maintain the internal environment of the body stable with respect to the changes occurring in the external environment. This process is coordinated by the body tissues, organs as guided by the nervous system of the body.

The homeostatic regulation includes three components these includes the receptor, control center and effector.

The receptor receives the information from the environment or tissues or organs. The control center processes the information. The control center transfers the information to the effector responds to the stimulus. For example in the case of regulation of the temperature of the body, there are temperature receptors present in the skin, which transfers the information to the brain, the brain acts as a control center and the effector are the blood vessels and sweat glands in the skin which provide cooling in high external temperature condition.
