    The hormone glucagon causes the release of of glucose (sugar) from body cells into the bloodstream. Its secretion is controlled by a negative-feedback system between the concentration of glucose in the blood and the glucagon-secreting cells in the pancreas. Therefore, which of the following statements is correct?
    • A. 

      A decrease in blood glucose concentration stimulates glucagon secretion, which in turn further lowers the blood glucose concentration.

    • B. 

      An increase in blood glucose concentration stimulates glucagon secretion, which in turn lowers the blood glucose concentration.

    • C. 

      A decrease in blood glucose concentration stimulates glucagon secretion, which in turn increases the blood glucose concentration.

    • D. 

      An increase in blood glucose concentration inhibits glucagons secretion, which further increases the blood glucose concentration.

  • 7. 
    Which of the following is an example of negative feedback?
    • A. 

      If body temperature increases above normal, thermoreceptors in the hypothalamus send signals to the brain. Certain areas of the brain then send signals to the nerves that control the sweat glands and blood vessels near the surface of the skin to make the sweat rate increase and surface blood vessels increase in diameter, which in turn reduces body temperature.

    • B. 

      If blood pressure increases above normal, baroreceptors in major arteries detect the change and send signals to the brain. Certain areas of the brain then send signals to the nerves that control the heart and blood vessels to make the heart beat slower and the blood vessels increase in diameter, which in turn reduce the blood pressure.

    • C. 

      If blood osmolarity increases above normal, osmoreceptors in the hypothalamus detect the change and cause the release of ADH from the posterior pituitary. ADH causes the kidneys to retain water as well as increase thirst which in turn decreases the blood osmolarity.

    • D. 

      If body temperature decreases below normal, thermoreceptors in the hypothalamus send signals to the brain. Certain areas of the brain then send signals to the nerves that control the major skeletal muscles and blood vessels near the surface of the skin to bring about shivering and surface blood vessels decrease in diameter, which in turn increases body temperature.

    • E. 

      All of the above are examples of negative feedback.
