The Wonders of the Placenta: Your Baby’s First Lifeline
The placenta is one of nature’s most extraordinary creations—an organ that exists only during pregnancy, yet works harder than almost any other organ in the body. It grows alongside your baby, nurtures them for nine months, and then completes its role once your little one is safely in your arms.
Let’s take a closer look at how the placenta forms, what it does, how it’s birthed, and the choices families have once its work is done. Shortly after conception, when the fertilized egg implants in the wall of the womb, special cells begin forming the placenta. By around 12 weeks of pregnancy, it’s fully developed and continues to grow as your baby does. What’s amazing is that the placenta is formed by both you and your baby, yet functions as one seamless unit—a bridge that connects two lives
The Placenta’s Role in Pregnancy
Think of the placenta as your baby’s lifeline. It’s a busy organ, performing several jobs at once, and here’s how it actually does it:
Nutrition and oxygen: Tiny blood vessels in the placenta lie right next to your own blood supply. Without the two ever mixing, nutrients (like vitamins, minerals, glucose, and proteins) and oxygen are passed across from your blood into your baby’s umbilical cord. It’s like a customised delivery system that makes sure your baby gets exactly what’s needed for growth.
Waste removal: As your baby takes in food and oxygen, they also produce waste products (like carbon dioxide and urea). These pass back across the placenta into your bloodstream. Your body then clears them out, just like it would with your own waste. In other words, the placenta acts like a “shared filter” between you and your baby.
Hormone production: The placenta is also a hormone factory. It releases hormones such as progesterone and estrogen to keep the womb lining strong and healthy, while another hormone, hCG, helps sustain early pregnancy. Later on, it makes relaxin and oxytocin-related hormones to prepare your body for labor and breastfeeding. These chemical messengers make sure your body and baby stay in sync.
Protection: While not a perfect barrier, the placenta helps block many bacteria and toxins from reaching your baby. It also “teaches” your immune system not to reject your baby, who is genetically part you and part your partner. In this way, the placenta acts like a shield, balancing connection and protection.

When Things Don’t Go as Planned
Sometimes, conditions of the placenta can affect pregnancy. Examples include placenta previa (when it covers the cervix), placental abruption (when it separates too early), or a placenta that doesn’t work as efficiently as it should.

This is why your healthcare team checks placental function during scans and monitors your pregnancy closely if there are concerns. Interestingly, the placenta can also serve as a kind of “black box”—just like in aviation. If complications occur in pregnancy or birth, the placenta can be sent for histological testing. This can provide doctors with valuable insights into what happened and help guide future care.
When the Placenta Can No Longer Fully Do Its Job
As your pregnancy goes beyond 40 weeks, the placenta can gradually become less efficient at supplying oxygen and nutrients to your baby. This doesn’t mean problems always occur, but it’s why healthcare providers monitor post-term pregnancies more closely, often with extra ultrasounds, non-stress tests, or Doppler scans. Signs that the placenta might be underperforming include reduced fetal movements or changes seen on these tests. Understanding this helps parents see why careful monitoring after your due date is important, ensuring your baby remains healthy until birth.
The Birth of the Placenta
After your baby is born, the placenta’s work continues for a short while. Mild contractions, often called “afterbirth pains,” help the placenta detach naturally from the uterine wall. There are two main ways the placenta can be delivered:
Active delivery: Your healthcare provider may give a medication (usually oxytocin) and gently guide the placenta out. This is called active management and is done to help the uterus contract firmly, reduce the risk of heavy bleeding, and make the process quicker and safer.
Passive (physiological) delivery: In this approach, the placenta is allowed to separate and deliver naturally without medications. You and your baby can rest, and the placenta is delivered when it is ready. This method can feel more gentle and less medicalized, but requires careful monitoring for any signs of bleeding.
After delivery, the placenta is examined to ensure it’s intact, because any retained tissue can cause bleeding or infection. Your midwife or Obstetrician will check it carefully before you leave the birth room
What Happens to the Placenta Afterwards
Hospitals and birth facilities follow strict laws and hygiene measures for handling human tissue. The placenta is classified as human tissue, so if no further use is requested, it is disposed of according to regulations to prevent infection or contamination. Staff wear gloves, store the placenta safely if needed, and use approved methods for transport and disposal.
Many families, however, choose to do something meaningful with the placenta:
Encapsulation: Your placenta can be steamed, dried, and ground into capsules for postpartum use. Many parents work with trained and certified doulas, like Kefi the Doula, who handle every step hygienically and professionally.
“Black box” testing: If complications occurred during pregnancy or birth, the placenta can be sent for histological testing. Just like a black box in aviation, it can provide important insights into why issues occurred, helping Doctors guide future pregnancies and care.
Cultural or personal rituals: Some families bury the placenta, sometimes planting a tree above it as a symbol of new life and growth.
Lotus birth: The placenta remains attached to the baby until the umbilical cord naturally falls off, believed to allow a gentler transition for the newborn.
Keepsakes or art: Families may create prints or mementos from the placenta as a way to celebrate and remember the pregnancy.
By understanding both the medical protocols and the creative or meaningful options, parents can make informed choices about their placenta that feel right for them.
Honouring the Placenta
The placenta is more than just an organ—it’s your baby’s first home, first protector, and first source of nourishment. While its physical role ends with the birth, many families find comfort in acknowledging its importance and choosing a way to honour it. Whether it’s safely tested, encapsulated with the help of a doula like Kefi, buried in a meaningful ceremony, or simply let go under hospital protocols, the placenta’s impact is lasting. The placenta is a wonder of pregnancy. Knowing its role, the choices available to you, and the safe practices around it can help you make informed, personal decisions as you prepare for your baby’s arrival.
