HOMEOSTASIS: INTRO

homeostasis is the property of a system, either open or closed, that regulates its internal environment and tends to maintain a stable, constant condition - Claude Bernard



It is the process by which the body adjusts its functions to compensate for deficiency.

Homeostasis, in conclusion, is the physiology process of every living organism which keep the its internal environment in constant condition. The relatively stable conditions of the internal environment is result from the a physiology mechanism called NEGATIVE FEEDBACK CONTROL.




THis diagram shows NEGATIVE FEEDBACK CONTROL, or in this scenario it goes like this



- The level of glucose in the bloodstream drops.

The bodies requires glucose in cells to meet the demand for ATP (Adenosine TriPhosphate).

- The body detects this with a particular receptor designed for this function.


- These receptors release hormones ( the chemical message that initiate the start of the feedback mechanism)

- The hormones travel to their target and intiate a corrective response, in this case the target is the secretion of more glucose into the bloodstream.
