Homeostasis

Homeostasis is the balance of functions or levels in the body, returning biological variables to their biochemical baseline when perturbed and keeping them there.

 

Homeostasis uses hormones and other signals to control vital physiological processes.

These generally act in a negative feedback loop, forming a stable, self-adjusting mechanism.

Of course, feedback loops can be very complex, with the brain doing the controlling and neural and endocrine control interacting with each other.
