  • D

Homeostasis is the body’s thermostat when it comes to its comfort and efficiency. The word comes from the Greek, homeos and stasis, meaning similar and condition, respectively, and describes a state of the body where a stable equilibrium of internal functions exists. Homeostasis preserves the body’s internal sameness, particularly with heat, by resisting and smoothing out changes. Since it allows the body’s internal environment to be independent of the external environment, it gives the organism a great amount of flexibility.
