What is homeostasis?


Most people like or would like to lead a balanced life, in which they can have security regarding the stability of the different aspects that make it up.

In the same way, a biological process takes place in the organism that is present at all times, seeking a state of balance.

What is homeostasis?

Homeostasis is a biological process that allows the body to be in optimal conditions, establish a balance and equilibrium in relation to alterations that may arise internally and externally, in order to maintain proper functioning.

This process is maintained through various control mechanisms that function in cells, tissues, and organs.

The main components responsible for its maintenance are classified as:

-Control center.

-Effector.

-Stimulus.

-Feedback mechanism.

-Receiver.

Different processes constantly participate in homeostasis in order to maintain a balance by attending to the changes that arise externally and internally, this to adjust aspects in relation to:

– Acid concentrations.

-Electrolytes.

-Energy.

–Hormones.

-Blood sugar level.

-Oxygen.

-Blood pressure.

-Proteins.

-Temperature

Homeostasis: The Balance in Negative Feedback

It is a homeostatic concept in which a system or organism chooses an automatic and contrary response to the changes that are imposed on it.

In this case, the objective is to regulate the alteration that it suffered in relation to its previous state and return to it. In this way the body tries to reduce the impact caused by the internal or external factor.

Negative feedback can become abrupt and strong in the face of internal or external change, and in turn can be gradual so that during it, the body’s response can oscillate seen from the point of balance.

Homeostasis: The Balance in Positive Feedback

On the other hand, a positive feedback is one that, given the impact received, offers a response that favors the increase of said impact. This event can trigger a series of processes that promote a cycle that affects the body until it finds balance.

Balance will always be the goal, and the body finds the channels to achieve it.
