The belly button is a scar marking where the umbilical cord connected a baby to its mother, serving as a vital lifeline in the womb.
The Origin of the Belly Button: A Lifeline in the Womb
The belly button, scientifically called the navel or umbilicus, is more than just a simple scar on your abdomen. It’s a permanent reminder of your earliest connection to life itself. During fetal development, the umbilical cord links the baby to the placenta inside the mother’s womb. This cord acts as a conduit, supplying oxygen and nutrients while removing waste products. Once birth occurs and the umbilical cord is cut, what remains is the belly button.
This scar varies in appearance from person to person—some are innies, others outies—and each shape carries no significant health implications but adds to human uniqueness. The belly button’s function during gestation was crucial; without it, survival inside the womb would be impossible. It’s essentially the baby’s first lifeline.
How Does the Umbilical Cord Work?
The umbilical cord typically measures about 50-60 centimeters long and contains two arteries and one vein encased in a gelatinous substance called Wharton’s jelly. The arteries carry deoxygenated blood and waste from the fetus back to the placenta, while the vein delivers oxygen-rich blood and nutrients from the mother.
This system ensures that despite being physically separate from their mother, fetuses receive everything they need for growth and development. The belly button marks where this vital connection was once attached externally on your body.
Umbilical Cord Components and Their Roles
- Umbilical Vein: Carries oxygenated blood from mom to baby.
- Umbilical Arteries (two): Return deoxygenated blood from baby to mom.
- Wharton’s Jelly: Protects vessels from compression.
The Belly Button After Birth: From Functionality to Scar
After delivery, cutting and clamping of the umbilical cord are routine procedures. This causes cessation of blood flow through these vessels. The remaining stump attached to the infant gradually dries up and falls off within one to two weeks postpartum. What remains is a small scar—the belly button.
While it no longer serves any physiological purpose after birth, it holds significance as a biological marker of prenatal life. Interestingly, some cultures have rituals or beliefs surrounding care for this area during infancy because infection risks exist at this site until healing completes.
The Healing Process of the Umbilical Stump
The stump goes through several stages:
- Initial drying: The stump turns dark brown or black as it dries.
- Detachment: Usually falls off between 7-14 days after birth.
- Healing: Skin closes over leaving behind a navel scar.
Proper hygiene during this phase is essential to prevent infections such as omphalitis—a serious but rare condition.
Belly Button Types: Why Do They Differ?
Humans have two main types of belly buttons: innies and outies. The difference arises mainly due to how skin heals after umbilical cord detachment and underlying tissue structure.
- Innie: Most common type; skin folds inward creating a concave shape.
- Outie: Less common; protrudes outward due to excess scar tissue or incomplete closure.
Neither type affects health or function since neither serves any purpose post-birth besides being an anatomical feature.
Belly Button Shape Influences
Factors influencing belly button shape include:
- The way umbilical cord was cut or clamped at birth.
- The amount of scar tissue formed during healing.
- The thickness of abdominal muscles beneath.
- An umbilical hernia can sometimes cause an outie appearance temporarily or permanently if untreated.
Belly Button Hygiene: Why It Matters
Though it no longer performs its original function, proper care of your belly button remains important throughout life. It’s often overlooked but can harbor dirt, sweat, dead skin cells, bacteria, and fungi due to its recessed structure (especially in innies).
Neglecting hygiene may lead to unpleasant odor or infections such as fungal overgrowth or bacterial dermatitis. Cleaning with gentle soap and water regularly helps maintain cleanliness without irritation.
Belly Button Cleaning Tips
- Use mild soap with warm water during showers.
- Avoid harsh scrubbing; gentle cleaning prevents skin damage.
- If you have an outie, cleaning is easier but still important.
- If you notice redness, discharge, or pain, consult a healthcare provider promptly.
Belly Button Piercings: A Modern Twist on an Ancient Mark
Belly button piercings have become popular fashion statements worldwide. They highlight this unique body feature while adding personal style flair. However, piercing through this area requires caution because it involves puncturing skin close to scar tissue that may heal differently than other body parts.
Proper aftercare minimizes risks like infection or scarring complications following piercing procedures.
Piercing Care Essentials
- Avoid touching with dirty hands during healing period (usually 6-12 months).
- Clean regularly with saline solution recommended by professionals.
- Avoid swimming pools or hot tubs until fully healed due to bacteria exposure risk.
Belly Button in Medical Contexts: More Than Just Cosmetic
Though often overlooked medically once healed post-birth, clinicians sometimes use the belly button as an anatomical landmark for surgeries or diagnostic procedures involving abdominal organs.
For example:
- Laparoscopic Surgery Entry Point: Surgeons often insert instruments near or through the navel because it provides direct access with minimal scarring visible afterward.
- Physical Examination Reference: Doctors use its position relative to other body parts when assessing abdominal pain or organ enlargement.
- Disease Indicators: Certain diseases cause visible changes around this area—like Sister Mary Joseph’s nodule indicating possible internal malignancies appearing as lumps near the navel.
The Belly Button Across Species: Is It Unique To Humans?
Humans aren’t alone in sporting navels; all placental mammals have them because they develop via an umbilical connection during gestation. However, appearances vary widely depending on species anatomy and how fur covers them post-birth.
For example:
- Cats and dogs have small fur-covered navels that are rarely noticeable without close inspection.
- Larger mammals like elephants also possess navels but concealed beneath thick skin folds or hairless patches.
- Marsupials lack traditional navels since their young develop differently outside wombs attached via pouches instead of placentas connected by cords.
This highlights how evolutionary biology shapes even tiny details like belly buttons across species lines.

Frequently Asked Questions
What Is The Belly Button For During Pregnancy?
The belly button marks where the umbilical cord connected the baby to the mother in the womb. It served as a vital lifeline, supplying oxygen and nutrients while removing waste, essential for fetal growth and development before birth.
What Is The Belly Button After Birth?
After birth, the umbilical cord is cut and the remaining stump dries and falls off, leaving the belly button. Though it no longer has a physiological function, it remains as a scar symbolizing the baby’s prenatal connection to its mother.
How Does The Belly Button Relate To The Umbilical Cord?
The belly button is the external scar left where the umbilical cord was attached. This cord contained blood vessels that transported oxygen and nutrients from mother to baby and removed waste products during pregnancy.
Why Does The Belly Button Have Different Shapes?
The shape of the belly button varies because of how the umbilical stump heals after birth. Some people have innies, others outies, but these differences are purely cosmetic with no impact on health or belly button function.
Is The Belly Button Important After Birth?
After birth, the belly button no longer serves a biological purpose but remains significant as a reminder of prenatal life. It also requires care during infancy to prevent infection until fully healed from the umbilical stump detachment.
The Fascinating Answer – What Is The Belly Button For?
The belly button stands as a permanent reminder of our earliest biological connection—the umbilical cord that once sustained us inside our mother’s womb. Though stripped of its original function after birth, it remains an intriguing anatomical feature reflecting human development history.
It signals where life-supporting vessels once passed vital nutrients and oxygen before birth but now serves as nothing more than a unique mark on our bodies.
