Vedclass · Answer

(A) The process of childbirth,known as parturition,is induced by a complex neuroendocrine mechanism.$1$. The signals for parturition originate from the fully developed fetus and the placenta,which induce mild uterine contractions called the fetal ejection reflex.$2$. This reflex triggers the release of oxytocin from the maternal pituitary gland.$3$. Oxytocin acts on the uterine muscle and causes stronger uterine contractions,which in turn stimulate further secretion of oxytocin.$4$. This stimulatory reflex between the uterine contraction and oxytocin secretion continues,resulting in stronger and stronger contractions,eventually leading to the expulsion of the baby out of the uterus through the birth canal.
