What is the Homeostasis|Physiology-The law CH1|the country of human body

II) Homeostasis: –

Now, we know that Homeostasis is the mechanisms used to maintain constant or stable internal environment. And this is the role of physiology; maintain stable internal environment.


Actually, the automated coordinating mechanisms of physiology make each agency or organ to perform its function that helps in maintaining constant internal environment. For example, if the oxygen content in the extracellular fluid is decreased due to decrement of the oxygen supply or increment of the need for oxygen, the automated coordination mechanisms will supply oxygen where it makes the lungs (Air-Supplying Agency) increase the oxygen supply to blood to compensate the oxygen needed by the cells.

In this series that will be a book in the future, we will talk about the automated coordination system that controls the internal environment or the extracellular fluid by making an automatic coordination between each agency (organ) to operate in support of each other.

In this title of homeostasis, we will talk about the 2 important processes that require the important automated coordination mechanisms, which are obtaining food or supplying nutrients and waste removal.

What does any country need to achieve these 2 processes? Any country needs coordination between agencies to obtain food or find food resources, agencies to remove wastes and agency for transporting foods and take the wastes away to the drainage. This is what we will talk about in this title.

Of course, there are many processes that require coordination between the country agencies such as maintain constant temperature for the country. However, for now, we will talk about the most important processes we mentioned earlier.
