In a normal mammalian birth,how does the body guarantee that birth proceeds to completion?
A)Via positive feedback -- stretching of the uterus by the descending fetus induces release of oxytocin from the posterior pituitary causing even stronger uterine contractions.
B)Via negative feedback -- stretching of the uterus by the descending fetus induces release of FSH and LH from the posterior pituitary causing even stronger uterine contractions.
C)Via positive feedback -- stretching of the uterus by the descending fetus induces release of prolactin from the posterior pituitary causing even stronger uterine contractions.
D)Via negative feedback -- stretching of the uterus by the descending fetus induces release of prostaglandins from the posterior pituitary causing weaker uterine contractions.

During mammalian birth, the body guarantees that birth proceeds to completion via positive feedback. The stretching of the uterus by the descending fetus induces release of oxytocin from the posterior pituitary, which causes even stronger uterine contractions. This positive feedback loop continues until the baby is born.
