  82. define homeostasis
    The ability or tendency of an organism or cell to maintain internal equilibrium by adjusting its physiological processes.
  83. explain a positive feedback loop
    • Positive feedback loops enhance or amplify changes; this tends to move a
    • system away from its equilibrium state and make it more unstable.
  84. explain a negative feedback loop
    • Negative feedbacks tend to dampen or buffer changes; this tends to hold a
    • system to some equilibrium state making it more stable.
  85. name two positive feedback loops found in the body
    1. blood platelet accumulation, which, in turn, causes blood clotting in response to a break or tear in the lining of blood vessels.

    2. The release of oxytocin to intensify the contractions that take place during childbirth.
  86. name two negative feedback loops found in the body
    • 1. temperature control. The hypothalamus,
    • which monitors the body temperature, is capable of determining even the slightest variation of normal body temperature. Response to such variation could be stimulation of glands that produce sweat to reduce the temperature or signaling various muscles to shiver to increase body temperature.

    2. when the body is deprived of food. The body would then reset the metabolic set point to a lower than normal value. This would allow the body to continue to function, at a slower rate, even though the body is starving.
