The umbilical cord detaches from the placenta after birth and is expelled naturally or removed during delivery, ceasing its function in the mother’s body.
The Role of the Umbilical Cord During Pregnancy
The umbilical cord acts as a vital lifeline between the mother and her developing baby. Composed of two arteries and one vein encased in a gelatinous substance called Wharton’s jelly, it facilitates the exchange of oxygen, nutrients, and waste products. While the fetus relies completely on this connection for survival, the mother’s body supports this process through the placenta.
Throughout pregnancy, the umbilical cord grows alongside the fetus, extending roughly 50 to 60 centimeters in length by term. It twists and coils naturally to protect its delicate vessels from compression or injury. This remarkable structure ensures that oxygen-rich blood flows from the mother to the baby while carrying deoxygenated blood back to be filtered out.
The mother’s circulatory system does not directly connect to fetal blood; instead, substances pass through placental membranes by diffusion or active transport. This separation prevents immune rejection and allows selective transfer of nutrients and antibodies.
During Labor: Changes in Blood Flow and Function
As labor progresses toward delivery, several physiological changes occur involving the umbilical cord. Contractions cause intermittent reductions in blood flow through the placenta and cord, which is perfectly normal and safe for a healthy fetus. The cord’s coiled structure helps maintain patency despite these pressure changes.
Once the baby is born, breathing begins independently, and lung function replaces placental oxygenation. This shift causes rapid closure of fetal blood vessels within minutes after birth. The umbilical arteries constrict first, followed by the vein. These closures effectively stop blood flow through the cord.
Immediately after delivery, medical staff clamp and cut the cord close to the newborn’s abdomen. This procedure separates baby and placenta physically but leaves a small stump attached to the infant that will dry up and fall off within weeks.
What Happens To The Umbilical Cord In The Mother? Post-Delivery Fate
After birth, attention turns to what happens to what remains of this once-critical structure inside the mother’s body. The umbilical cord remains connected from the baby’s navel to the placenta still attached inside the uterus.
Once separated from the newborn, contractions continue as part of uterine involution—the process where the uterus shrinks back to pre-pregnancy size. These contractions help detach and expel the placenta along with its attached umbilical cord.
The entire placenta with its cord is delivered during what’s called “the third stage of labor.” This stage usually lasts 5 to 30 minutes but can extend longer if complications arise. Once expelled, healthcare providers examine both placenta and cord for completeness to ensure no fragments remain inside.
If any part of the placenta or umbilical cord remains embedded in uterine tissue—a condition known as retained placenta—it can cause heavy bleeding or infection. Prompt medical intervention is required in such cases.
The Placenta-Umbilical Cord Connection
The umbilical cord inserts centrally or eccentrically into one side of the placenta’s fetal surface. It serves as a conduit for fetal blood vessels branching out over placental tissue to maximize nutrient exchange.
When labor ends and placental separation occurs, this connection breaks down at its attachment point inside the uterus. The uterus contracts firmly at this site to seal maternal blood vessels that supplied blood to placenta tissue during pregnancy.
The Biological Breakdown of Umbilical Cord Tissue Inside The Mother
Once expelled along with the placenta, any residual tissue left behind undergoes natural biological degradation if not removed surgically or manually during delivery management.
Inside maternal tissues before expulsion, enzymes start breaking down components of both placental and umbilical tissues shortly after delivery begins. This enzymatic activity aids separation by weakening adhesion points between uterus lining (endometrium) and placental membranes.
If small bits of umbilical cord remain inside after delivery—usually due to incomplete removal—they can trigger inflammatory responses leading to postpartum hemorrhage or infection (endometritis). That’s why thorough examination post-delivery is crucial for maternal health.
How Medical Professionals Manage Umbilical Cord Expulsion
Obstetricians monitor signs indicating successful placental separation: lengthening of umbilical cord outside vaginal opening, sudden gush of blood from vagina (called “gush”), uterine firmness on palpation, and rise of uterine fundus in abdomen.
Controlled traction on the clamped cord may assist expelling placenta if it does not come out spontaneously within expected timeframes. However, excessive pulling risks uterine inversion—a rare but serious complication where uterus turns inside out due to improper force on cord.
If natural expulsion fails or complications arise like retained fragments or excessive bleeding, manual removal under anesthesia may be necessary. Surgical intervention like curettage (scraping) clears remaining tissue from uterus lining safely.
Umbilical Cord Clamping Timing: Impact on Mother and Baby
The timing of clamping influences both neonatal outcomes and maternal considerations indirectly related to what happens next with residual cords inside mothers.
Immediate clamping (within 15-30 seconds) stops placental transfusion quickly but may reduce newborn iron stores slightly compared with delayed clamping (1-3 minutes). Delayed clamping allows more blood transfer into baby but prolongs time before complete placental separation occurs for mother.
Some studies suggest delayed clamping may slightly increase risk of heavier postpartum bleeding due to prolonged placental circulation; however, differences are minimal when managed properly by skilled professionals.
Table: Comparison Between Immediate vs Delayed Umbilical Cord Clamping Effects
| Aspect | Immediate Clamping | Delayed Clamping |
|---|---|---|
| Neonatal Iron Stores | Lower iron reserves initially | Higher iron reserves for months |
| Placenta Expulsion Timing | Faster separation & delivery | Slightly delayed separation time |
| Postpartum Bleeding Risk | No significant increase observed | Slightly increased risk if unmanaged |
Umbilical Cord Complications Affecting Maternal Outcomes
Though rare, certain abnormalities involving umbilical cords can complicate delivery or postpartum recovery:
- Velamentous Cord Insertion: When vessels insert into membranes rather than directly into placenta; riskier for vessel rupture.
- Short Umbilical Cord: May cause difficulty delivering placenta or uterine inversion risk.
- Cord Prolapse: When cord slips ahead of baby during labor; emergency situation affecting both mother and fetus.
- Retained Umbilical Cord Fragments: Can cause infection if not fully expelled with placenta.
Addressing these complications promptly protects maternal health during recovery phases post-delivery.
The Healing Process After Placenta & Umbilical Cord Delivery
Once expelled completely from mother’s body, uterus continues contracting tightly over next several weeks—this process helps seal off blood vessels formerly supplying placenta site preventing hemorrhage.
Inside uterine tissue where attachment occurred, healing involves regeneration of endometrial lining replacing decidua basalis (specialized layer supporting pregnancy). Any minor trauma caused by detachment resolves naturally without scarring in healthy individuals.
Maternal hormones like oxytocin stimulate these contractions strongly right after birth; synthetic oxytocin is often administered when necessary to reduce bleeding risks related to incomplete placental separation including parts of umbilical cords left behind unintentionally.

Frequently Asked Questions
What happens to the umbilical cord in the mother immediately after birth?
After birth, the umbilical cord is clamped and cut near the baby’s abdomen, separating the newborn from the placenta still attached inside the mother. The cord within the mother remains connected to the placenta until it naturally detaches during the delivery of the placenta.
How does the umbilical cord detach from the mother’s body post-delivery?
The umbilical cord detaches from the placenta as the uterus contracts after birth. These contractions help expel the placenta and remaining cord, completing delivery. This natural process ensures that what remains of the umbilical cord is expelled without harm to the mother.
Does any part of the umbilical cord stay inside the mother after childbirth?
Yes, initially part of the umbilical cord stays inside attached to the placenta within the uterus. However, this part is delivered along with the placenta during the third stage of labor, so no part of the umbilical cord remains permanently inside the mother.
What role does uterine contraction play in dealing with the umbilical cord in the mother?
Uterine contractions after birth help separate and expel both the placenta and attached umbilical cord from inside the mother. These contractions also reduce bleeding by compressing blood vessels where the cord was attached, aiding in postpartum recovery.
Can any complications arise related to what happens to the umbilical cord in the mother?
Complications are rare but can include retained placental fragments or parts of the umbilical cord, which may cause bleeding or infection. Medical evaluation ensures that all placental tissue and cord remnants are fully expelled to prevent such issues.
Conclusion – What Happens To The Umbilical Cord In The Mother?
The journey of an umbilical cord doesn’t end at birth—it undergoes a complex process within a mother’s body before final expulsion alongside her placenta. After serving as an essential conduit throughout pregnancy, it detaches naturally due to enzymatic breakdown aided by uterine contractions during labor’s third stage. Medical professionals carefully manage this phase ensuring complete removal while monitoring for complications such as retained fragments that could threaten maternal health through bleeding or infection.
Understanding what happens to the umbilical cord in detail reveals how intricately designed childbirth processes are—not just for nurturing new life but also safeguarding mothers’ well-being during one of life’s most critical moments.
