Solution

Parturition is a process done by combined nerve hormonal regulation co-ordination. The signals for parturition originate from the fully developed fetus and the placenta which induce mild uterine contractions called foetal ejection reflex.

Oxytocin hormone plays part in parturition which acts on the uterine muscle and causes stronger uterine contraction. This leads to expulsion of the baby out of the uterus through the birth canal parturition.
