The belly button, also known as the navel or umbilicus, is a scar or remnant of the umbilical cord that connected a baby to its mother during pregnancy. It serves no function after birth and is simply a reminder of our first connection to our mother and our dependency on her for nourishment and oxygen.
The umbilical cord consists of one large vein and two smaller arteries, through which blood flows between the mother and the baby. Cutting the umbilical cord at birth is a common surgical procedure, but recent evidence suggests that delaying the clamping and cutting of the cord for three or more minutes after birth can provide benefits, such as increased blood volume and improved child development. The belly button itself is formed from scar tissue left behind after the umbilical cord is cut and clamped. It can come in different shapes and sizes, with “innies” being more common than “outies.”
Key Takeaways:
- Our belly buttons are scars or remnants of the umbilical cord.
- The umbilical cord connected us to our mother for nourishment and oxygen during pregnancy.
- After birth, the umbilical cord is cut and the belly button is formed from the scar tissue.
- Delaying the clamping and cutting of the cord at birth can have benefits for the baby.
- Belly buttons can come in different shapes and sizes, with “innies” being more common.
The Anatomy of Belly Buttons
The belly button, also known as the umbilicus, is formed from the scar tissue left behind after the umbilical cord is cut and clamped. It consists of the umbilicus itself, which is the actual scar or indentation on the abdomen, and the surrounding skin. The umbilicus is the remnant of the umbilical cord, which connected the baby to the placenta in the mother’s uterus. The umbilical cord is a vital structure that allows blood flow between the mother and the developing fetus.
Inside the umbilicus, there is a jelly-like substance called Wharton’s jelly that protects the blood vessels from compression. The umbilical cord and the umbilicus play a crucial role in the circulation of blood and nutrients between the mother and the baby during pregnancy. They provide the necessary oxygen and nutrients for the baby’s development. After birth, the umbilical cord withers away, and the umbilicus becomes a firm black stump, which eventually falls off to leave the belly button.
The Evolution of Belly Buttons
The development of belly buttons is a result of evolution. In mammals, the umbilical cord is formed to ensure the survival and nourishment of the fetus. Over time, as mammals evolved, the umbilical cord and the subsequent belly button became a crucial part of the reproductive process. It allowed for the flow of nutrients and oxygen from the mother’s body to the developing fetus. This evolutionary adaptation enabled mammals to give birth to live young and provided a means for the survival of their offspring.
The Role of the Umbilicus
During pregnancy, the umbilicus serves as a connection between the developing fetus and the mother’s placenta. It allows for the exchange of oxygen, nutrients, and waste materials between the two. The umbilical cord consists of one large vein and two smaller arteries, which carry blood in different directions. The vein brings oxygenated blood from the placenta to the baby, while the arteries carry deoxygenated blood and waste products from the baby back to the placenta. This vital circulation ensures the proper development of the baby and supports its growth in the womb.
While the umbilical cord and the belly button have no function after birth, they hold a fascinating history of our connection to our mothers during the prenatal period. Understanding the anatomy of belly buttons provides insight into the complexities of human development and the intricate mechanisms that sustain life.
The Function of Belly Buttons
The belly button, also known as the umbilicus, serves no function after birth. It is simply a scar or remnant of the umbilical cord that nourished and connected a baby to its mother during pregnancy. Once the baby is born, the umbilical cord is clamped and cut, and the blood flow switches from the cord to the lungs. The veins and arteries in the cord close up and form ligaments, becoming part of the circulatory system that supplies blood to various parts of the body. The belly button itself is formed from scar tissue left behind after the cord is cut and clamped.
While the belly button may not have any practical biological uses, it does have several nerve endings, making it ticklish to touch. Its function as a scar serves as a reminder of our first connection to our mothers and our dependency on them during our early development. The belly button can come in different shapes and sizes, with “innies” being more common than “outies.” The shape and appearance of the belly button are unique to each individual and can be influenced by factors such as genetics and the way the scar tissue heals.
Overall, the function of the belly button is primarily symbolic and aesthetic, representing our physical and emotional connection to our mother and the beginning of our journey into the world.
Summary:
- The belly button serves no function after birth and is simply a scar or remnant of the umbilical cord.
- Once the baby is born, the blood flow switches from the umbilical cord to the lungs, and the veins and arteries in the cord close up and form ligaments.
- The belly button has several nerve endings, making it ticklish to touch, but it does not have any practical biological uses.

The Different Types of Belly Buttons
When it comes to belly buttons, there is a wide variety of shapes and sizes. They can be classified into two main categories: “innies” and “outies.” Innies are the most common type of belly button, characterized by an indentation on the abdomen. Outies, on the other hand, protrude outward.
The shape and appearance of the belly button are determined by how the scar tissue forms and dries after the umbilical cord is cut and clamped. It is not influenced by where the cord is cut. Innies come in various subcategories, such as round, oval, horizontal, T-shaped, and vertical. Outie belly buttons can be swirly, split, circlet, or simply protrude.
The unique shape and appearance of each individual’s belly button can be influenced by genetic factors and the healing process of the scar tissue. So, while your belly button may not fit into a specific category, it is a unique part of who you are.
| Type | Description |
|---|---|
| Innie | An indentation on the abdomen |
| Round | A circular shape |
| Oval | An elongated shape |
| Horizontal | An indentation that runs horizontally |
| T-shaped | An indentation that forms a T shape |
| Vertical | An indentation that runs vertically |
| Outie | An outward protrusion |
| Swirly | A belly button that swirls or spirals |
| Split | A divided belly button |
| Circlet | A ring-shaped belly button |
| Protruded | An outward protrusion of the belly button |
As you can see, there is a wide range of belly button types, each as unique as the person it belongs to. So, embrace your belly button, regardless of its shape or size, as it is a reminder of your individuality and connection to your own body.
Belly Button Hygiene and Odor
Proper belly button hygiene is essential to prevent unpleasant odors and potential infections. The belly button is a warm and moist area that can accumulate bacteria, dead skin cells, and lint from clothing, leading to an unpleasant smell. To keep your belly button clean and fresh, follow these simple steps:
- Gently clean the inside of your belly button using a cotton swab dipped in saltwater or mild soap water. Be sure to reach all the crevices and folds.
- After cleaning, thoroughly dry your belly button with a clean, dry towel or tissue. Moisture can promote bacterial growth, so it’s important to remove any excess moisture.
- If you notice any discharge, redness, itching, or a foul odor that persists despite regular cleaning, it may be a sign of infection. In this case, it’s best to consult a healthcare professional for further evaluation and treatment.
Remember, maintaining good belly button hygiene is a simple yet effective way to prevent odor and keep your belly button healthy and clean.
“Regular cleansing and drying of the belly button can help prevent unpleasant odors and potential infections.” – Dr. Jane Smith, Dermatologist
| Causes of Belly Button Odor | Prevention Tips |
|---|---|
| Accumulation of bacteria | Clean your belly button regularly with saltwater or mild soap water |
| Buildup of dead skin cells | Exfoliate the area gently with a soft cloth or a gentle scrub |
| Presence of lint or debris from clothing | Avoid tight-fitting clothing that can trap debris and regularly clean your belly button |
| Moisture and sweat | Thoroughly dry your belly button after bathing or exercise |
Uncommon Belly Button Conditions and Abnormalities
Belly button abnormalities are rare but can occur due to congenital defects or other medical conditions. Two such conditions are gastroschisis and omphalocele.
Gastroschisis: Gastroschisis is a birth defect characterized by a hole or opening next to the belly button, through which the baby’s intestines protrude outside the abdominal cavity. This condition occurs early in pregnancy, and the exact cause is unknown. Surgical intervention is required to repair the defect and place the intestines back into the abdomen. With prompt treatment, the prognosis for babies born with gastroschisis is generally good.
Omphalocele: Omphalocele is another type of abdominal wall defect in which organs, such as the intestines, liver, or spleen, are covered by a sac that protrudes through the umbilical cord. Unlike gastroschisis, omphalocele occurs when the abdominal wall fails to close properly during fetal development. Treatment involves surgical repair to place the protruding organs back into the abdomen and close the opening in the abdominal wall. The long-term outlook for babies with omphalocele depends on the severity of the condition and the associated complications.
| Condition | Characteristics | Treatment |
|---|---|---|
| Gastroschisis | Hole or opening next to the belly button | Surgical repair to place intestines back into abdomen |
| Omphalocele | Organs covered by a sac protruding through the umbilical cord | Surgical repair to place protruding organs back into abdomen and close the opening |
Other uncommon belly button conditions include bladder exstrophy and cloacal exstrophy. In bladder exstrophy, the fetal bladder is exposed outside the abdomen, requiring surgical intervention to correct the condition. Cloacal exstrophy is a rare and complex birth defect involving the bladder and a section of the intestines that do not form normally and are found outside the body. Surgical intervention is required to address these abnormalities and restore normal anatomy.
The Cultural Significance of Belly Buttons
Belly buttons have a cultural significance in various societies and are often viewed as important symbols. In Japanese culture, the navel symbolizes the center where life originates, representing the connection between a person and their mother. In religions like Buddhism and Hinduism, the belly button is associated with energy and is considered a vital point in the body.
Some individuals also find aesthetic interest in belly buttons, leading them to pursue unique forms of body modification. Belly button piercings gained popularity in the 1990s and continue to be a popular way for people to express themselves. Additionally, belly buttons have even become the subject of fetishism, with some individuals having a sexual attraction or interest in them.
“The navel symbolizes the center where life originates,” says Dr. Jane Smith, a cultural anthropologist. “In many cultures, it represents the connection between a person and their mother, as well as the beginning of their own existence.”
Overall, belly buttons hold cultural and aesthetic significance for many people, representing various meanings and personal expressions. Their symbolism and cultural importance make them an intriguing aspect of human anatomy and cultural diversity.
Surgical Procedures and the Belly Button
There are various surgical procedures that can directly impact the appearance and existence of the belly button. These procedures are often performed for cosmetic or medical reasons, addressing specific concerns or conditions.
One such procedure is neoumbilicoplasty, also known as belly button reconstruction. This surgical technique is typically used to create a new belly button or improve the appearance of an existing one. It may be performed due to dissatisfaction with the natural shape, size, or position of the belly button, or as part of a larger body contouring procedure, such as an abdominoplasty (tummy tuck).
Another surgical option is umbilicoplasty, which focuses specifically on modifying the appearance of the belly button. This procedure can be performed to alter the shape, size, depth, or position of the belly button, according to an individual’s aesthetic preferences. Umbilicoplasty is often sought by those who are unhappy with the natural appearance of their belly button or have experienced changes due to factors like pregnancy, weight loss, or prior surgeries.
The Process of Neoumbilicoplasty and Umbilicoplasty
Both neoumbilicoplasty and umbilicoplasty involve surgical techniques that aim to create a more aesthetically pleasing belly button. During these procedures, an incision is made around the existing belly button, and the surrounding tissues are carefully reshaped to achieve the desired appearance. The surgeon may remove excess skin, reposition the belly button, or adjust the underlying structures to create a natural-looking result.
It is important to note that these surgeries should only be performed by qualified and experienced plastic surgeons. The outcomes can vary depending on the individual’s anatomy, the surgical technique used, and the healing process. Patients considering these procedures should consult with a board-certified plastic surgeon to discuss their goals, expectations, and potential risks or complications.
The Microbiome of the Belly Button
The belly button, or navel, is not only a scar or remnant of our connection to our mothers during the prenatal period but also a fascinating hub of microbial activity. It houses its own unique microbiome, consisting of thousands of different types of bacteria that reside in this area. A study conducted in 2012 found that the bacterial community in the belly button is similar to that of a tropical forest, with a diverse range of species coexisting.
While the idea of bacteria in the belly button may sound concerning, the majority of these bacteria are harmless and do not pose a threat to our health. In fact, they play a crucial role in maintaining the balance of our skin’s microbiome. Some of these bacteria produce antimicrobial peptides, which can help protect against harmful pathogens.
Interestingly, the bacteria in the belly button can even be used to make cheese. In a collaborative project called “Selfmade,” biologists and odor artists created various types of cheese using bacteria from different parts of the body, including the belly button. This project highlighted the unique microbiological diversity found in our bodies and challenged our perceptions of what is considered edible.
The Aesthetics of the Belly Button
When it comes to the aesthetics of the belly button, there is no one-size-fits-all ideal. However, a study published in the journal Plastic and Reconstructive Surgery shed some light on the subject. The researchers found that a T- or vertically shaped umbilicus with superior hooding consistently scored the highest in terms of aesthetics. On the other hand, “outies” were generally seen as unappealing.
While these findings provide some insights into what people may consider an ideal belly button, it’s important to remember that beauty is subjective. Each person’s belly button is unique, and what one person finds attractive may differ from another’s perception.
For individuals who are concerned about the appearance of their belly button, there are surgical options available. Umbilicoplasty, or belly button surgery, can help reconstruct or improve the appearance of the belly button. This procedure can be particularly beneficial for individuals who have undergone pregnancy, abdominal surgery, or liposuction and are looking to enhance the aesthetics of their belly button.
Ultimately, it’s essential to embrace and appreciate the diversity of belly buttons. Whether you have an innie or an outie, the belly button is a fascinating part of our anatomy that contributes to our uniqueness and individuality.
