    Study Notes

    Introduction to Feedback Mechanisms

    • Feedback mechanisms are physiological loops, either amplifying or inhibiting a biological pathway.
    • Homeostasis is the body's stable internal state. Maintaining homeostasis involves mechanisms like temperature regulation and osmotic balance.

    Thermoregulation

    • Animals regulate their body temperature through internal or external means.
    • Ectotherms gain heat from their environment, while endotherms generate internal heat.
    • Negative feedback mechanisms are involved in regulating body temperature, either raising or lowering it.

    Osmoregulation

    • Osmoregulation is the process of maintaining salt and water balance in the body.
    • Electrolytes are compounds that dissociate into ions in water.
    • Osmoregulatory organs help maintain dissolved ion concentrations within fluids.
    • Osmoregulation involves a complex interaction of stimulus, sensor, control centre, and effector.

    Types of Feedback Loops

    • Negative feedback: A loop that counteracts a stimulus, keeping a variable within a set point. Examples include body temperature regulation and blood glucose control.
    • Positive feedback: A loop that intensifies a response until an endpoint is reached. Examples include blood clotting and childbirth.

    Importance of Homeostasis

    • Homeostasis, a state of internal equilibrium, is essential for an organism's survival.
    • Maintaining this equilibrium allows cells and tissues to maintain ideal functions, even in changing conditions.

    Key Terms

    • Homeostasis: A stable internal environment of an organism.
    • Ectotherm: An animal that relies on external sources of heat for temperature regulation.
    • Endotherm: An animal that produces its own heat to regulate body temperature.
    • Osmoregulation: The process of maintaining fluid balance inside the body.
    • Negative Feedback Loop: A feedback loop that works to maintain a stable internal environment by reducing a response to an external stimulus.
    • Positive Feedback Loop: A feedback loop that causes a response to progressively increase.
