HOMOEOSTASIS Meaning and
Definition
-
Homeostasis is a fundamental biological process that refers to the ability of an organism or a system to maintain a stable internal environment despite external fluctuations or changes. It involves a dynamic balance or equilibrium within the body that ensures optimal functioning and physiologic stability. The term "homeostasis" was first coined by the American physiologist Walter Cannon in the early 20th century.
Homeostasis operates through a series of intricate feedback mechanisms that tightly regulate various factors, such as body temperature, blood glucose levels, pH balance, and fluid balance. These mechanisms enable the body to respond to changes and maintain a relatively constant internal environment within narrow limits.
The control of homeostasis relies on two main components: the receptor and the effector. Receptors detect changes in the internal or external environment, such as temperature sensors or chemical receptors in the blood. Effector organs, such as muscles or glands, then respond to the signals received from the receptors by making the necessary adjustments to restore balance within the body.
Failure to maintain homeostasis can lead to various physiological disorders or diseases. For example, conditions like hypertension, diabetes, or hyperthermia can arise when the body is unable to properly regulate blood pressure, glucose levels, or body temperature, respectively.
In conclusion, homeostasis is a crucial process that allows organisms to maintain a stable internal environment necessary for their survival and optimal functioning. It ensures the balance of various physiological parameters and enables the body to respond and adapt to changes in the external environment.

Etymology of HOMOEOSTASIS
The word "homeostasis" comes from the combination of two Greek words: "homeo", meaning "similar" or "same", and "stasis", meaning "standing" or "position". The term was coined by the American physiologist Walter Bradford Cannon in the 1920s to describe the self-regulating processes that maintain stability and balance within living organisms.
