Homeostasis is any
self-regulating process by which biological systems tend to maintain stability
while adjusting to conditions that are optimal for survival. It is the stable

homeostasis usually involves negative feedback loops. These loops act to oppose
the stimulus, or cue, that triggers them. The stable condition is the condition
of optimal functioning for the organism, and is dependent on many variables,
such as body temperature and fluid balance, being kept within certain pre-set
limits.
