The “stability” that the organism reaches is rarely around an exact point (such as the idealized human body … Homeostasis: A property of cells, tissues, and organisms that allows the maintenance and regulation of the stability and constancy needed to function properly. The control of blood glucose level is a good example of homoeostasis. Due to the high level of potassium, aldosterone stimulates the excretion of excess potassium from the body and normalizes the potassium level in plasma.

Homeostasis, while described here with examples from human physiology, is a fundamental property of life and a necessity for survival of all living things — not just humans but all other animals as well as bacteria, plants, fungi, and protists. Homeostasis is a regulatory procedure. Homeostasis is the tendency to resist change in order to maintain a stable, relatively constant internal environment. The tendency to maintain, or the maintenance of, normal internal stability in an organism by coordinated responses of the organ systems that automatically compensate for environmental changes. There are three essential components of all homeostatic control mechanisms: control center, receptor, and effector. Normal physiology requires a pH balance of fluids inside the body.
