The placenta is expelled shortly after birth, completing the third stage of labor and ensuring the uterus contracts to prevent bleeding.
The Final Act: Placenta After Delivery- What Happens
The moment a baby takes its first breath, the placenta’s role shifts dramatically. This remarkable organ, which has supported the fetus throughout pregnancy, now prepares to exit the mother’s body. The process of delivering the placenta marks the third and final stage of labor, often overlooked but crucial for maternal health.
After the baby is born, contractions continue but usually become less intense. These uterine contractions help detach the placenta from the uterine wall. Within 5 to 30 minutes post-delivery, the placenta separates and moves down through the birth canal. This event is sometimes called “afterbirth.” The mother might feel mild cramping or pressure as she pushes out this organ.
Once expelled, healthcare providers inspect the placenta carefully. They check that it is complete because any retained fragments can cause serious complications such as heavy bleeding or infection. The uterus then contracts firmly to close off blood vessels where the placenta was attached, preventing hemorrhage.
Physiological Changes During Placenta Delivery
The delivery of the placenta involves complex physiological mechanisms designed to protect both mother and child. After birth, oxytocin—a hormone released naturally or administered via injection—stimulates uterine contractions. These contractions compress blood vessels that were supplying blood to the placenta.
This compression is vital because it minimizes postpartum bleeding by sealing off open vessels in the uterine lining. Without proper contraction of the uterus after placental delivery, a condition called postpartum hemorrhage can occur, which remains one of the leading causes of maternal mortality worldwide.
The placenta itself detaches along a natural plane between its maternal side (attached to uterine wall) and fetal side (connected via umbilical cord). This separation occurs as weakened attachment points give way under continued uterine contractions.
Stages of Placenta Separation
The process typically follows three recognized stages:
- Contraction Phase: Uterus tightens and begins to shrink.
- Detachment Phase: Placenta loosens from uterine wall.
- Expulsion Phase: Placenta moves through cervix and vagina for delivery.
Each phase is essential for a smooth transition from pregnancy to postpartum recovery.
Examination and Handling of Placenta Post-Delivery
Once delivered, careful examination of the placenta provides critical information about pregnancy health and potential complications. Midwives or obstetricians inspect both sides—the maternal surface with its rough texture and cotyledons (lobes), and the smooth fetal surface covered by amniotic membrane.
They look for:
- Completeness: Missing pieces can indicate retained tissue.
- Size and Weight: Typical weight ranges from 500g to 600g at term.
- Appearance: Abnormalities like calcifications or infarcts may signal issues during pregnancy.
- Cord Insertion: Normally central; deviations may affect fetal circulation.
If any abnormalities are detected, further medical evaluation may be necessary.
The Fate of Umbilical Cord and Membranes
The umbilical cord remains attached until after placental delivery but is clamped and cut soon after birth. The membranes surrounding the fetus are also expelled with the placenta. In some cases, these membranes may tear or remain partially inside, which requires manual removal by healthcare providers.
The Role of Active Management in Placental Delivery
Active management refers to medical interventions designed to facilitate timely placental delivery and reduce risks such as hemorrhage. This approach typically includes:
- Administration of Oxytocin: To stimulate strong uterine contractions immediately after birth.
- Controlled Cord Traction (CCT): Gentle pulling on umbilical cord while supporting uterus helps deliver placenta faster.
- Uterine Massage: Encourages contraction post-delivery.
Studies show active management reduces severe bleeding compared to expectant management where no intervention is applied unless necessary. However, some debate remains regarding routine use versus selective application based on individual risk factors.
Natural vs Medical Placenta Delivery
Expectant or physiological management allows placenta delivery without drugs or traction, relying solely on natural contractions. While this can be gentler for some women, it carries a slightly higher risk of prolonged third stage labor or hemorrhage in certain cases.
Medicalized delivery speeds up placental expulsion but might cause discomfort or other side effects due to medications like synthetic oxytocin.
The Importance of Uterine Contraction Post-Placenta Delivery
After placental expulsion, sustained uterine contraction is critical for compressing blood vessels at implantation sites. Failure in this mechanism leads to excessive bleeding known as postpartum hemorrhage (PPH).
PPH remains a major obstetric emergency worldwide; thus monitoring uterine tone immediately after delivery is standard practice. Healthcare staff palpate the uterus regularly during this period ensuring it feels firm rather than boggy or relaxed.
If signs point toward poor contraction (uterine atony), interventions such as additional oxytocin doses, massage, or surgical procedures might be necessary promptly.
A Closer Look at Postpartum Hemorrhage Risks
Several factors influence PPH risk related to placental delivery:
| Risk Factor | Description | Impact on Placental Delivery |
|---|---|---|
| Retained Placenta Fragments | Tissue left inside uterus post-delivery. | Makes uterus unable to contract fully; increases bleeding risk. |
| Placenta Accreta Spectrum | Aberrant invasion into uterine wall layers. | Difficult separation; may require surgery. |
| Prolonged Labor / Multiple Pregnancies | Tired uterus loses contractile strength. | Poor contraction post-placenta expulsion leads to hemorrhage. |
| Use of Certain Medications | Sedatives or magnesium sulfate may relax uterus too much. | Makes controlling bleeding harder after placental delivery. |
Understanding these risks helps healthcare providers prepare appropriate care plans during delivery.
The Aftermath: Healing Following Placental Delivery
Once delivered safely without complications, healing begins immediately. The uterus gradually shrinks back toward pre-pregnancy size over several weeks—a process called involution—and bleeding reduces steadily as healing progresses inside.
Mothers often experience vaginal discharge known as lochia for up to six weeks post-birth; it’s partly composed of blood mixed with remnants from placental attachment sites healing inside.
Proper rest combined with attentive postpartum care ensures optimal recovery from both childbirth and placental delivery phases.

Frequently Asked Questions
What happens to the placenta after delivery?
After delivery, the placenta is expelled during the third stage of labor. Uterine contractions help detach it from the uterine wall, allowing it to pass through the birth canal within 5 to 30 minutes after birth. This process is essential to prevent excessive bleeding.
How does the placenta separate from the uterus after delivery?
The placenta separates along a natural plane between its maternal and fetal sides. Uterine contractions weaken attachment points, causing the placenta to loosen and detach. This detachment is a critical step before the placenta is expelled from the mother’s body.
Why is it important to deliver the placenta after birth?
Delivering the placenta is crucial because retained placental fragments can cause heavy bleeding or infection. Once expelled, healthcare providers examine it to ensure completeness, helping prevent serious postpartum complications and promoting maternal health.
What physiological changes occur during placenta delivery?
During placenta delivery, oxytocin stimulates uterine contractions that compress blood vessels where the placenta was attached. This compression seals off vessels, minimizing postpartum bleeding and reducing risks like hemorrhage, which is vital for a safe recovery.
What sensations might a mother feel when delivering the placenta?
Mothers often experience mild cramping or pressure as they push out the placenta. These sensations result from continued uterine contractions and are generally less intense than labor pains but are important for successfully expelling the organ.
Conclusion – Placenta After Delivery- What Happens Explained Clearly
Placenta After Delivery- What Happens reflects an essential but often unseen stage in childbirth that seals a successful transition from pregnancy to motherhood. The timely expulsion of this organ relies on coordinated uterine contractions stimulated naturally or medically.
