Sequence for Parturition
Parturition is the process of giving birth to a baby. It involves a series of events that lead to the expulsion of the fetus from the mother's uterus. The correct sequence for parturition to occur is as follows:
Signal from fetus and placenta
- The fetus and placenta release signals that indicate the readiness for birth. These signals trigger the next steps in the process.
Release of oxytocin
- The signal from the fetus and placenta stimulates the release of oxytocin hormone from the mother's pituitary gland. Oxytocin plays a crucial role in inducing uterine contractions.
Uterine contractions
- Oxytocin causes the muscles of the uterus to contract. These contractions help to push the fetus down the birth canal.
Rise in oxytocin secretion
- As labor progresses, the secretion of oxytocin increases, leading to more frequent and powerful contractions.
Powerful contractions
- The increasing strength of the contractions helps to further dilate the cervix and push the baby through the birth canal.
Parturition
- Finally, the culmination of these events results in the successful delivery of the baby, marking the completion of parturition.
Therefore, the correct sequence for parturition to occur is:
Signal from fetus and placenta → Release of oxytocin → Uterine contractions → Rise in oxytocin secretion → Powerful contractions → Parturition.

- Parturition starts with the signal released by the fetus and the placenta.
- These act on the pituitary to release oxytocin.
- Oxytocin acts as a stimulant leading to contractions of the uterine muscles.
- The uterine contractions feedbacks to release more oxytocin from the pituitary.
- This results in more powerful contractions of the uterus until the baby is delivered in the process of parturition.
