Parturition
- The average duration of human pregnancy is about 9 months which is called the gestation period.
- Vigorous contraction of the uterus at the end of pregnancy causes expulsion/delivery of the foetus.
- This process of delivery of the foetus (childbirth) is called parturition.
- The signals for childbirth originate from the fully matured foetus and placenta which induce mild uterine contraction called the foetal ejection reflex.
- This leads to the release of oxytocin from the posterior pituitary gland of the mother.
- Parturition begins with a series of involuntary contractions of the uterus that are experienced as labour pains.
- The contraction of the uterine muscles is increased by oxytocin.
- Relaxin increases the flexibility of the pubic symphysis and dilates the uterine cervix during labour pains.
- This leads to the expulsion of the baby out of the uterus through the birth canal – parturition.
- Soon after the infant is delivered, the placenta is also expelled out of the uterus.
- In about 28-35 days, the uterus returns fully to its nonpregnant state by a reduction in size and restoration of the endometrium of the uterus.
