Maintenance of constancy or a high degree of uniformity in functions of an organism or interactions of individuals in a population or community under changing conditions, because of the capabilities of organisms to make adjustments.
In medicine and biology, this term is applied to the inherent tendency in an organism toward maintenance of physiological and psychological stability.
(= homoeostasis) The tendency towards a relatively constant state. A variety of homoeostatic mechanisms operate to keep the properties of the internal environment of organisms within fairly well-defined limits.
Homeostasis, also spelled homoeostasis (from Greek: ὅμοιος, `hómoios`, `similar`), is the property of a system in which variables are regulated so that internal conditions remain stable and relatively constant. Examples of homeostasis include the regulation of temperature and the balance between acidity and alkalinity (pH). It is a pro...Found on http://en.wikipedia.org/wiki/Homeostasis
- control of an organism`s internal environment. Water content, temperature, acid-base balance, level of oxygen and carbon dioxide, adequate supply of energy are some of the many factors in the organism which require monitoring and control. A common form of control is feedback.Found on http://www.eclipse.co.uk/moordent/page5.html

(homeo- + Gr. stasis standing) a tendency to stability in the normal body states (internal environment) of the organism. It is achieved by a system of control mechanisms activated by negative feedback; e.g. a high level of carbon dioxide in extracellular fluid triggers increased pulmonary ventilation, which in turn causes a decrease in carbon dio.....Found on http://users.ugent.be/~rvdstich/eugloss/DIC/dictio39.html

A state of balance among all the body systems needed for the body to survive and function correctly. In homeostasis, body levels of acid, blood pressure, blood sugar, electrolytes, energy, hormones, oxygen, proteins, and temperature are constantly adjusted to respond to changes inside and outside the body, to keep them at a normal level.Found on http://www.cancer.gov/dictionary?expand=H

Our body's natural state is one of internal balance or homeostasis. Regards flight or flight, when the danger is over the parasympathetic branch of our autonomic nervous system, antagonistic to the sympathetic branch, returns our body to its more natural state of homeostasis, or internal balance. Imagine what would happen without this!
