Homeostasis refers to the ability of a cell or body to maintain a condition of equilibrium of concentration within its internal environment. An example is humans’ internal body temperature. When an individual is healthy, his/her body temperature maintains a temperature of 98.6˚ Fahrenheit. You can learn more about how the body regulates heat here. Some other examples of homeostasis are pH and nutrient levels.
