Homeostasis is understood as the set of self-regulation phenomena that allow the maintenance of a relative constancy of the conformation and properties of the internal environment of an organism.

Homeostasis is the ability of the body to present a unique and constant physicochemical situation within certain limits, even in the face of alterations or changes imposed by the environment or the environment.

For homeostasis to occur in the body, the body mobilizes the various systems (self-regulation) such as the central nervous system, excretory system, endocrine system, circulatory system, respiratory system, etc. To keep the conditions of life firm.

In this way, homeostasis, by extension, points to the characteristics of any system, whether open or closed, that allows it to regulate the internal environment to achieve stable maintenance.

Examples of Homeostasis

1. 1. Oxygen homeostasis for cells

At high altitudes, such as the Alps, the Andes, the Pyrenees or the Himalayas, the oxygen in the air that is present in the atmosphere is less than at the surface. The respiratory activity of the people inhabiting these regions becomes insufficient in a regular rhythm.

However, to compensate for this difficulty, the organism or the body makes use of a homeostatic means: intensification of the respiratory rhythm, so that later the production of red blood cells slowly increases, which will then be released into the bloodstream.

With higher numbers of red blood cells , the individual can efficiently retain the lungs of the little O² that is present in the air.

1. Psychological homeostasis

Internal imbalances can occur psychologically, and this is called needs.

In the field of psychology, homeostasis is distinguished by the balance that exists between the needs and satisfaction of the individual.

In this way, if the individual does not feel that their needs have been met, homeostasis encourages them to achieve an internal balance through behaviors that allow them to satisfy those needs.

1. Cell metabolism homeostasis

The chemical structure of the internal metabolism must not be altered and must remain unchanged.

For these reasons, the resulting products, newly formed after cellular metabolism (CO², urea, ammonia, uric acid, urates, creatinine, etc.) need to be discarded immediately. This expulsion is done through the lungs (CO²) , through the sweat and sebaceous glands, but basically through the kidneys.

1. Homeostasis in ecology

Ecological homeostasis is characterized by the dynamic balance that exists between the natural communities in their environment . When this balance disappears due to various causes such as floods, earthquakes, droughts, among others. The homeostasis capacity disappears generating an ecological balance.

1. Cybernetic homeostasis

This involved the creation of a homeostatic that regulated itself through feedback. It was the invention of an English physician William Ross Ashby, in the mid-20th century.

Cybernetic homeostasis allows various electronic systems to maintain a state of equilibrium before a series of variables.

1. Homeostasis in business administration

In the area of business administration , it is considered that a company works in a homeostatic way, because it must change its behavior every time there are changes in the market, in order to maintain its market share, and remain within the competition
