Meaning of Homeostasis

What is Homeostasis:

The set of self-regulation phenomena that allow the maintenance of relative constancy in the composition and properties of the internal environment of an organism is known as homeostasis.

Homeostasis is the organism's ability to present a characteristic and constant physical-chemical situation within certain limits, even in the face of alterations or changes imposed by the environment or the environment.

How is homeostasis produced in the body? The body or organism mobilizes the different systems (self-regulation), such as the central nervous system, the endocrine system, the excretory system, the circulatory system, the respiratory system, etc., to keep life conditions constant.

Thus, homeostasis, by extension, refers to the characteristic of any system, whether open or closed, that allows it to regulate the internal environment to maintain a stable condition.

Origin of the word homeostasis

The term homeostasis is of Greek origin; It comes from the word "homoios", which means "same or similar", and "stasis" which expresses "stability".

The term was coined by the American physiologist Walter Bradford Cannon, in the year 1929. By this term, Bradford Cannon did not refer to a static situation, but to something that varies within tight and precise limits. In fact, most of physiology focuses on studying and analyzing the limits of variation and the mechanisms of regulation.

In 1859, the French physiologist Claude Bernard, expressed that all vital mechanisms, however varied they may be, have no other objective than to maintain the conditions of stability of the internal environment.

Psychological homeostasis

Internal imbalances can occur on a psychological level, and this is called needs.

In the case of psychology, homeostasis is characterized by the balance that exists between the needs and satisfaction of an individual.

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

Oxygen homeostasis for cells

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

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

With a higher rate of red blood cells, the individual can efficiently retain the little O² that is available from the air in the lungs.

Cell metabolism homeostasis

The chemical composition of the internal environment must not be altered and must remain unchanged.

Therefore, the resulting newly formed products after cellular metabolism (CO², urea, ammonia, uric acid, urates, creatinine, etc.) must be discarded immediately.

This expulsion is done through the lungs (CO²), through the sweat and sebaceous glands, but mainly through the kidneys.

Homeostasis in business administration

In the field of the administration of a company, we can affirm that a company behaves in a homeostatic way, since it must change its behavior every time new modalities are presented in the market, in order to maintain its market share, and stay in the competition.

Homeostasis in ecology

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

Cybernetic homeostasis

Cybernetic homeostasis involved the creation of a homeostat that was self-regulating through feedback. It was the invention of the English physician William Ross Ashby, in the mid-20th century.

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