Even though we do not realize it, our bodies are constantly working to adjust copious body functions to acclimate to the physical environment to maintain equilibrium or balance in our internal environment. This process that the body self-regulates serves to maintain stability through the biological systems is known as homeostasis (Encyclopedia Britannica, 2015). Homeostasis is described as the body’s ability to maintain relatively stable internal conditions, even with the outside world constantly changing. The literal translation of homeostasis is “unchanging”, however this doesn’t mean that it is an unchanging state, it indicates a “dynamic state of equilibrium” or a balance. Homeostasis involves almost every organ system in the body, and the interaction comprises of chemical, neutral, and thermal factors (Marieb & Hoehn, 2015, 10).
Homeostasis works to maintain the organism's internal environment, where the body's processes are able to function at a level that would allow life to continue in that organism. The three systems which are controlled by homeostasis are the respiratory, …show more content…

Heat loss in humans is aided by reduction of activity, by perspiration, and by heat-exchange mechanisms that permit larger amounts of blood to circulate near the skin surface (Encyclopedia Britannica, 2015). Homeostasis also acts on maintaining our blood pressure and heart rates within normal parameters. The average human heart rate is approximately 70 beats per minute, but varies greatly from person to person (Langley, 1965, 47). Negative feedback systems regulate hundreds of different variables including body temperature, blood sugar levels, blood volume, heart rates (HR), breathing rates, blood pressure (BP), and blood levels of oxygen, carbon dioxide and minerals (Marieb & Hoehn, 2013,
