The body maintains balance through a process known as homeostasis, which involves keeping the body internally steady while adjusting to outward conditions.
What Is Homeostasis?
Homeostasis is any kind of automatic process that a living thing does in order to maintain the internal steadiness of its body while adjusting to its external environment. The body undergoes such changes in order to survive and function properly.
When homeostasis is achieved, the levels of the body constantly rise and fall as a response to the changes inside and outside of the body. Some of the body's self-regulating systems include blood pressure, blood sugar, energy, oxygen, acid levels, temperature, proteins, electrolytes, and hormones.
An organism's health and life result from regulation through homeostasis. When homeostasis is interrupted, disease may result. It is a crucial concept that combines both self-regulation and physiology in order to keep the internal environment stable.
Once homeostasis is properly done, the living thing will keep on living. However, when it becomes unsuccessful, the imbalance could result in disease or death. Proper therapy and treatment should focus on resetting homeostasis conditions.

How Homeostasis Works
There are three mechanisms that are generally involved in homeostasis. These are the effector, control center, and receptor. All of these work with each other in order to keep the body's balance by picking up changes and acting upon them in order to keep systems regulated.
The receptors are often organs, tissues, and cells. They monitor the environment to pick up any changes. They then notify the control center once they detect anything.
The control center, or integration center, are typically found in the brain and help determine what normal balance is for the body. It also determines what can be done in order to correct anything that deviates from the body's normal state. This center will then instruct the effectors to act on these instructions.
The effectors, which are organs, tissues, and cells, will make the body react in order to correct any imbalance and ultimately restore balance. An example of this is sweating, which helps lower the temperature of the body when a person gets too hot.
Feedback System
A crucial part of homeostasis is that the internal environment of a living thing is maintained via a self-regulating system that manages within a narrow value range. Homeostasis is maintained through feedforward and feedback.
A feedback system refers to a closed-loop structure that handles future actions through feeding past internal environment changes to the system. Such a system then alters behavior in order to adjust with outward conditions.
Feedback systems have two types, namely, positive and negative ones. Positive feedback produces growth processes, wherein actions maximize results that could yield greater actions. On the other hand, negative feedback has a target and addresses any failures in meeting such a target.
