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.
