When a woman goes into the first stage of labor, the oxytocin level in her plasma is 40 pg/ml, but during the second

stage of labor it is 123 pg/ml. Once the baby has been delivered the mother's oxytocin level is 64 pg/ml. Which type of feedback

mechanism is occuring?

A. Negative feedback

B. Positive feedback

"It is a physiological regulation system in a living body that works to return the body to its normal internal state (or homeostasis)."
It is of two types: positive feedback mechanism and negative feedback mechanism.

In positive feedback mechanism: when activation of one component leads to the activation of another, it is known as positive feedback.

Example: During childbirth, the oxytocin level of a women into her first stage of labor is 40 pg/ml for uterine contraction, which activate more release of oxytocin for further contraction.

In negative feedback mechanism: when activation of one component leads to the inactivation of another, it is known as negative feedback.

Example: when blood glucose level increase, the insulin are secreted which lowers the glucose level in blood.

Hence, the correct option is: B. Positive feedback.
