 Homeostasis: Meaning, Definition, and Importance

 What is Homeostasis?

Homeostasis is the process by which an organism maintains a stable internal environment despite external changes. It ensures that temperature, pH levels, water balance, and other physiological conditions remain within a narrow, optimal range for survival.

 Definition of Homeostasis

“Homeostasis is the tendency of an organism to regulate its internal environment to maintain a stable and constant condition, regardless of external changes.”

Walter Cannon (1926) defined it as “the ability of an organism to maintain internal stability through self-regulating mechanisms.”

 Examples of Homeostasis

Body Temperature Regulation

Blood Sugar Regulation

Water Balance in Cells

 Why is Homeostasis Important?

Maintains optimal conditions for cellular function
Prevents diseases caused by extreme changes in the body
Helps organisms adapt to their environment

 How Does Homeostasis Work?

Homeostasis is maintained through feedback mechanisms:
Negative Feedback (Most Common)  – Counteracts changes to restore balance.

 Final Thoughts

Homeostasis is essential for survival, keeping our body functioning smoothly. Without it, even small environmental changes could be deadly!
