Sara is giving birth to her first child. She is concerned that her labor is taking longer than she thought it would. Why does giving birth usually take time for the contractions to proceed to the point when the child is born? explain to Sara the child birth process using what you learned about homeostasis, identify the feedback system and all the components of this feedback.

Solution

Release of oxytocin during labour pains is the best example of positive feedback regulation. In this, the initial release of oxytocin triggers uterine contraction.

Increased uterine contractions further stimulate the posterior pituitary to release more oxytocin, this positive loop control results in abnormal raise of oxytocin levels that are very essential during child birth. After delivery, the uterine muscles relax, allowing the oxytocin levels to decrease. This is an example of positive feedback regulation.
