    Study Notes

    Homeostasis

    • Refers to the maintenance of a stable internal environment within an organism despite external fluctuations.
    • Achieved through a delicate balance of physiological processes to ensure optimal function.

    Key Aspect of Homeostasis

    • Dynamic Equilibrium: The body continuously adjusts and responds to internal and external changes to maintain a relatively stable internal environment.

    Regulation of Homeostasis

    • Nervous System: Plays a central role in regulating homeostasis by detecting changes in the internal environment, sending signals, and triggering appropriate responses.

    Disruption of Homeostasis

    • Dehydration: A decrease in bodily fluids would disrupt the balance of electrolytes and water in the body, impacting various physiological functions.

    Mechanism of Homeostasis

    • Negative Feedback Loop: A regulatory mechanism where a change in the internal environment triggers a response that counteracts the change, restoring balance to the system.
