Homeostatic regulation involves three parts or mechanisms: 1) the receptor, 2) the control center and 3) the effector. The receptor receives information that something in the environment is changing. The control center or integration center receives and processes information from the receptor.
Homeostasis is important throughout biology because as homeostasis is balanced/regulated it allows organs, bodily functions etc. to work optimally as the right amounts of horm â¦ ones, composites, temperatures and many other factors are working properly.omeostasis is what regulates your body temperature and keeps you at a constant temperature, for humans it is 98.6 F.
