Troyanec [42]

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.
