The placenta, post-delivery, appears as a dark reddish-blue, disc-shaped organ, typically 6-8 inches wide and 1 inch thick, with two distinct sides.
Understanding the body’s processes during and after childbirth can bring a sense of calm and insight. The placenta, an organ often discussed but less frequently seen, plays an extraordinary role in nourishing a baby throughout pregnancy. Once the baby arrives, the placenta follows, and seeing it for the first time can be a moment of curiosity for many new parents.
The Placenta’s Vital Role During Pregnancy
Before exploring its appearance after birth, it’s helpful to appreciate the placenta’s function. This temporary organ develops in the uterus during pregnancy, acting as the baby’s life support system. It facilitates the exchange of nutrients, oxygen, and waste products between the mother and the developing fetus.
The placenta also produces essential hormones, such as progesterone and estrogen, which are crucial for maintaining the pregnancy and preparing the mother’s body for birth. It effectively acts as a filter, protecting the baby from certain bacteria and viruses while allowing beneficial antibodies to pass through, offering passive immunity.
What Does Placenta Look Like After Birth? — The Visuals Explained
After your baby is born, the uterus contracts again to expel the placenta, often referred to as the “afterbirth.” This event marks the third stage of labor. When it emerges, the placenta has a distinct appearance, characterized by its shape, color, and two unique surfaces.
It generally looks like a large, flat, somewhat oval or round piece of tissue. Its overall impression is that of a dense, meaty organ. Observing it can offer a tangible connection to the incredible biological processes that just occurred.
The Maternal Side: Rough and Lobed
The side of the placenta that was attached to the uterine wall is known as the maternal side. This surface has a rough, bumpy, and somewhat spongy texture. It’s divided into distinct sections called cotyledons, which are individual lobes separated by grooves.
These cotyledons are where the maternal blood vessels intertwined with the placental tissue to facilitate nutrient and gas exchange. The color here is typically a deep, dark reddish-blue or maroon, reflecting the rich blood supply that was present. This side can sometimes have remnants of maternal blood clots or tissue attached.
The Fetal Side: Smooth and Shiny
In contrast, the fetal side, which faced the baby, is remarkably different. It’s covered by a thin, translucent membrane called the amnion, giving it a smooth and shiny appearance. Beneath the amnion lies the chorion, another membrane.
The umbilical cord emerges from this side, usually near the center, though sometimes it can be attached off-center. You can often see the intricate network of blood vessels branching out from the umbilical cord across the fetal surface, resembling the branches of a tree. These vessels carried oxygen and nutrients to the baby and removed waste products.
Size and Weight Considerations
The size and weight of a full-term placenta can vary, but there are typical ranges. It generally measures about 6 to 8 inches (15-20 centimeters) in diameter and is approximately 1 inch (2-2.5 centimeters) thick at its thickest point. Its weight is usually around 1 to 1.5 pounds (450-700 grams), which is roughly one-sixth the weight of the baby it supported.
Factors such as maternal health, fetal growth, and gestational age can influence the placenta’s final dimensions. For example, a larger baby might correlate with a slightly larger placenta, as the organ adapts to meet the growing demands for nutrient transfer. According to the American College of Obstetricians and Gynecologists, the placenta’s health and integrity are vital indicators of a healthy pregnancy outcome, and its examination post-delivery can provide important insights into maternal and fetal well-being.

Color and Texture Nuances
Beyond the primary reddish-blue, the placenta’s color can exhibit subtle variations. Areas might appear darker or lighter depending on blood flow and any localized changes. The overall texture is soft and somewhat gelatinous, yet firm enough to hold its shape.
The membranes surrounding the placenta, the amnion and chorion, are typically pale and translucent. These membranes form the amniotic sac, which cushioned and protected the baby throughout pregnancy. Observing their intactness is also part of the post-delivery examination.
| Characteristic | Description |
|---|---|
| Shape | Disc-shaped, oval, or round |
| Diameter | 6-8 inches (15-20 cm) |
| Thickness | 1 inch (2-2.5 cm) at center |
| Weight | 1-1.5 pounds (450-700 g) |
| Color | Dark reddish-blue, maroon |
The Third Stage of Labor: Placental Expulsion
The expulsion of the placenta is a natural and expected part of childbirth. After the baby is born, the uterus continues to contract, albeit less intensely. These contractions help to shear the placenta from the uterine wall.
Signs that the placenta is ready to be delivered include a sudden gush of blood, lengthening of the umbilical cord outside the vagina, and a change in the shape of the uterus from discoid to globular. Healthcare providers often assist this process through gentle traction on the umbilical cord and uterine massage, a practice known as active management of the third stage of labor, which helps reduce the risk of postpartum hemorrhage.
Post-Delivery Examination: What Providers Look For
After the placenta is delivered, healthcare providers meticulously examine it. This examination is crucial for ensuring that the entire placenta has been expelled and for identifying any potential issues that might affect the mother’s recovery or provide insights into the baby’s health. The integrity of the placenta, including its shape, size, and completeness, is carefully assessed.
Providers look for any missing pieces, which could indicate retained placental fragments in the uterus, a condition that can lead to excessive bleeding or infection. They also check for abnormalities in the umbilical cord’s insertion point, the number of vessels (typically two arteries and one vein), and any unusual lesions or discolorations on the placental tissue. This examination helps confirm the health of the pregnancy and delivery. Research published by the National Center for Biotechnology Information highlights the importance of placental pathology in understanding pregnancy complications and fetal outcomes.

| Aspect | Significance |
|---|---|
| Completeness | Ensures no retained fragments, preventing hemorrhage/infection. |
| Membranes | Checked for intactness and tears, indicating fetal health. |
| Umbilical Cord | Number of vessels (2 arteries, 1 vein), insertion site, length. |
| Cotyledons | Assessed for integrity and any missing lobes. |
| Overall Condition | Presence of clots, calcifications, or unusual lesions. |
Variations and Anomalies
While the general description of the placenta holds true for most births, variations can occur. These might include differences in shape, such as a bilobed (two-lobed) or succenturiate (accessory lobe) placenta. The umbilical cord can also have different insertion points, like a marginal or velamentous insertion, where vessels run through the membranes before reaching the placental disc.
Sometimes, calcifications or infarcts (areas of dead tissue) can be observed on the placenta, which may or may not have clinical significance depending on their extent. These variations are typically identified during the post-delivery examination and are noted in the medical record.
Cultural Perspectives on the Placenta
Across various cultures, the placenta holds diverse meanings and traditions. Some cultures view it as sacred, burying it with specific rituals, believing it connects the child to the earth or ancestors. Others have traditions of planting a tree over the buried placenta, symbolizing the child’s growth and life.
In some traditions, the placenta is honored for its life-giving properties and is seen as the baby’s first companion. These practices reflect a deep respect for the organ’s role in sustaining life and highlight the cultural significance attributed to this often-unseen part of the birth experience.
What Does Placenta Look Like After Birth? — FAQs
Is it normal for the placenta to be different colors?
Yes, the placenta can have varying shades, primarily dark reddish-blue or maroon. Areas might appear slightly darker due to concentrated blood or lighter if blood flow was less intense in a particular region. The membranes covering the fetal side are typically pale and translucent.
How long does it take for the placenta to be delivered after the baby?
The placenta is usually delivered within 5 to 30 minutes after the baby’s birth. This period is known as the third stage of labor. Active management techniques, such as administering oxytocin and gentle cord traction, can help expedite this process safely.
Can I ask to see my placenta after birth?
Absolutely, many parents choose to see their placenta after birth. Most hospitals and birth centers accommodate this request. It’s a personal choice, and discussing it with your healthcare provider beforehand can ensure your wishes are respected.
What happens to the placenta after it’s delivered?
After delivery and examination by healthcare providers, the placenta is typically disposed of as medical waste. However, some parents choose to keep it for cultural practices, encapsulation, or other personal reasons. Discussing these options with your birth team is recommended.
Does the placenta feel painful when it comes out?
The expulsion of the placenta usually involves mild contractions, often described as less intense than labor contractions. Most individuals feel pressure or a sensation of fullness, but significant pain is uncommon. Any discomfort is typically brief and manageable.
