In biology used to describe a condition where an organism maintains a stable structure where in fact a constant flux of molecules occurs. Although many organisms can live for years, all cellular components like proteins, membranes, sugars, and nucleic acids are constantly recycled while never compromising the integrity of the organism as a whole. This turnover processes can be characterized by specific half-life values that for most proteins, membranes, and RNA (but not DNA structures) are measured in hours. In a more narrow sense homeostasis refers to the maintenance of water and salt concentration in cells.
the maintenance of stable, internal conditions within specific limits. A characteristic of all living systems.
the process in which the internal environment exists at a steady-state equilibrium despite changes in the external environment.
A Greek word used in biology to describe the balancing act required to keep a complicated system functioning. For the immune system, homeostasis refers to maintaining the balance of different cell types (naive, memory, B-cells, CD4 T-cells, CD8 T-cells) required for healthy immune function.
the process by which the body brings into play certain mechanisms to maintain stability in its internal environment.

A state of physiological equilibrium produced by a balance of the functions and chemical composition within the body.
the state in which a dynamic equilibrium is reached; for instance, the body tries to keep energy levels at a constant level. When energy gets low, we eat. This brings energy levels back up until our body exhausts that supply, and then we eat again.
Resistance to change. The ability of a system to self-regulate and maintain a particular state.
A condition in the body where all organs, systems and processes are functioning in balance and harmony. The checks and balances are operating properly and there is neither too much activity nor too little. Homeostasis equals health.

The tendency of the body to maintain an internal equilibrium.
Maintenance of a relatively stable or balanced internal body state despite environmental fluctuations.

This is the tendency of a physiological system (i.e., a neuron, neural system or the body as a whole) to maintain its internal environment in a stable equilibrium
(home´ ee o sta´ sis) [Gr. homos: same + stasis: position] • The maintenance of a steady state, such as a constant temperature or a stable social structure, by means of physiological or behavioral feedback responses.
Homeostasis has been defined as the "coordinated physiological processes which maintain most of the steady states in the organism" (Cannon, 1939). The term 'sleep homeostasis' refers to the sleep-wake dependent aspect of sleep regulation. Thus homeostatic mechanisms counteract deviations of sleep from an average "reference level" by augmenting sleep propensity when sleep is curtailed or absent, and reducing sleep propensity in response to excess sleep.
The use of feedback systems to keep a desired state. Often used to describe physiological steady-states. See also: Feedback.
hoo-me-OH-Stay-siss) A level of stability in an ecosystem. This can apply to any size or scale, even in a micro-sized form.
Homeostasis means balance or dynamic equilibria. Our bodies are always trying to maintain a state of balance, or homeostatic state, no matter how precarious it is. The goal of mineral balancing programs is to move the body from a less desirable state of balance to a more desirable homeostatic state - one associated with better health.
Active control to maintain relatively constant conditions.
The tendency of a system, especially the physiological system of higher animals, to maintain internal stability, owing to the coordinated response of its parts to any situation or stimulus tending to disturb its normal condition or function. Capacity to adapt.
One of the most important features of a biotic community is that is possesses mechanisms for self-regulation. All communities, except possibly the very simplest types, contain within themselves regulatory mechanisms which enable them constantly to adjust themselves to the changing conditions of their physical environments. This ability for self-regulation is called "homeostasis". cf. feedback. Homozygous (Homozygote) Having identical genes of a gene pair present in the same organism.
The body's tendency to maintain the conditions of its internal environment by various forms of self-regulation.
A state of equilibrium or balance among various fluids and chemicals in a cell, in tissues, or in the body as a whole.
(HOH-mee-oh-STAY-sis) 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.
Regulatory mechanisms, for instance, the nervous system, which keep our body temperature constant OR the mechanism that maintains the carbon dioxide-oxygen balance in the atmosphere.
Maintenance of relatively constant internal conditions in the face of a varying external environment.
Homeostasis is the physiological process by which the internal systems of the body (e.g. blood pressure, body temperature, acid-base balance) are maintained at equilibrium despite variations in the external conditions.

Homeostatic systems keep body temperature, water balance, energy balance, etc., close to critical goal values. When the state deviates from the goal value, the homeostatic system activates a response that will correct the deviation.

A state of balance in the body maintained by several complex biological mechanisms that operate to offset disruptive changes.
The process of keeping the internal environment of the body stable by making adjustments to changes in the external environment.
Homeostasis is the property of an open system, especially living organisms, to regulate its internal environment to maintain a stable, constant condition, by means of multiple dynamic equilibrium adjustments, controlled by interrelated regulation mechanisms. The term was coined in 1932 by Walter Bradford Cannon from the Greek homoios (same, like, resembling) and stasis (to stand, posture).
