Question 20 of 42

1

A Receptor

(ie feedback system)

Select one of the following:

  • is a body structure that monitors changes in a controlled condition and sends input to a control center.

    (example, the pancreas detects low blood glucose in the blood.)

  • in the body, for example, the brain, sets the range of values within which a controlled condition should be maintained

  • reverses a change in a controlled condition

  • tends to strengthen or reinforce a change in one of the body’s controlled conditions

Explanation

Question 21 of 42

3

A Positive Feedback System

may be more then one right answer;

Select one or more of the following:

  • tends to strengthen or reinforce a change in one of the body’s controlled conditions

  • does not occur often in a controlled system

  • reverses a change in a controlled condition

  • is a body structure that monitors changes in a controlled condition and sends input to a control center

  • an example would be during childbirth contractions of the wall of the uterus force the baby’s head into the cervix, stretching the cervix. Stretch receptors detect this and send signals to the brain which releases the hormone oxytocin. Oxytocin makes the muscles of the uterus contract even harder, forcing the baby deeper into the cervix which causes even more stretching of the cervix.
