Homeostasis is the process by which an organism maintains a stable internal environment despite changes in the external environment. Homeostasis is essential for life, as it allows the body or a cell to function properly even in the face of changing conditions.  When homeostasis is disrupted, it can lead to a variety of health problems.

Some examples of homeostasis in the body include:

  • The regulation of body temperature through sweating and shivering


  • The regulation of blood pressure through the constriction and dilation of blood vessels


blood pressure

  • The regulation of blood sugar levels through the release of insulin and glucagon


blood sugar

  • The regulation of water balance through the kidneys



Homeostasis is a complex process that is essential for life. It is made possible by the coordinated efforts of many different organs and systems in the body.
