The homeostasis of the human body works like a machine set at a particular standard. If the factors deviate from the standard values, the homeostatic mechanism come into action.
For example, if a cell requires certain protein, the respective genes get a signal and get activated. The cell start synthesizing the protein and when sufficient amount is made, there is a feedback loop, which allows the same protein to stop the synthesis as well. A lot of organs and cellular systems are involved in regulating the synthesis of this protein.
This is similar to the cooling system. If we set the temperature of the cooling system to certain degree, it will start cooling the room till the required temperature is reached. As soon as the temperature is acquired, the system cut-off automatically and the required temperature is maintained.
Answer: By Hormonal action and Nervous coordination
Explanation:
Hormones are substances produced by one tissue and conveyed by the bloodstream to another to effect physiological activity. Homeostasis is the maintenance of a stable internal environment in the body.
Body systems such as digestive, circulatory, excretory systems etc, all are coordinated to achieve a STABLE INTERNAL ENVIRONMENT by the aid of HORMONES AND/OR NERVOUS COORDINATION.
For Example: the vasodilation of blood vessels during hot weather, and the opposite action of vasoconstriction during cold weather are both controlled by Hormonal action and nervous coordination which leads to a stable body temperature preventing excess heat accumulation.
Also, Nervous system controls the body systems, such that the muscle contractions are joined to actions like sweating, breathing, respiration etc
So, to maintain homeostasis hormonal action and Nervous coordination is necessary.
