Which human body function is NOT controlled through negative feedback mechanism?
Correct answer: C. Labor contraction
- A. Body temperature
- B. Glucagon production
- C. Labor contraction
- D. Parathyroid activity
Explanation
Oxytocin stimulates the muscle contractions that push the baby through the birth canal. The release of oxytocin result in stronger or augmented contractions during labor. Thus Labour contraction is an example of positive feedback.

About Chemical Coordination and Hormones
Chemical coordination uses hormones released by endocrine glands and carried in blood to specific target cells. Coverage includes the pituitary, thyroid, pancreas, adrenal glands, ovaries and testes, feedback control, and the contrast between slower, longer-lasting hormonal responses and rapid nervous coordination.
