All mammals are born attached to the mother with an umbilical cord. After this connection is broken, the navel is tightened and becomes invisible, and only in people it remains for the rest of their lives. What happens to this part of the body when a person grows up?

During the first hours of life

As you know, after birth, independently or with the help of a midwife, the child takes the first breath, and the blood passes through his veins to the lungs, which previously did not perform their functions. The alveoli open, the arteries contract, and blood flow to the placenta stops, and the umbilical vein slowly fades. Now obstetricians cut this bond between the infant and the mother.

Neonatologists from Northern State Medical University, Russia, in the Neonatological Practice Guide, explain that at this point, the internal veins and arteries in the umbilical cord close and form ligaments, which are tough connective tissue. These ligaments remain attached to the inside of the navel. Some of the remaining umbilical arteries become part of the circulatory system and provide blood to the bladder, ureters, and vas deferens in male infants.

Domestic doctors also warn that sometimes babies have a vessel that previously connected the bladder to the umbilical cord. In this case, urine is periodically excreted from the child's navel, and then this pathology is routinely operated on.

In childhood

In most cases, an umbilical hernia appears in children at an early age - up to 5 years. Representatives of the American Academy of Pediatrics in the memo for young colleagues explain that normally, after the umbilical cord falls off in newborns, the umbilical ring closes and the opening is obliterated by scar-connective tissue.

But if the navel node is swollen, redness is noticeable on the skin, then this means that the increase in intra-abdominal pressure has contributed to the release of the intestinal loops, the greater omentum and the peritoneum into the umbilical space. The occurrence of intra-abdominal pressure can have a variety of reasons, ranging from the development of constipation in a child to Harler's disease. But the enlarged and inflamed navel takes on a normal appearance and minimal boundaries after surgical treatment. It is called hernioplasty and is performed using local tissues or using mesh implants.

It should be noted that the formation of an umbilical hernia in a child has nothing to do with the technique of processing the umbilical cord at the time of birth.

In later life

Throughout adulthood, a person rarely pays attention to his navel. Usually he remembers this part of the body when intestinal or stomach pain is given to it.

Another option is to carry out conventional hygiene procedures, as a result of which obvious dirt is suddenly washed out of the umbilical fossa. Even people who take a shower every day have encountered such a phenomenon and this has interested scientists. A group of epidemiologists from North Carolina State University in Chapel Hill, USA, studied the navel for a year. To do this, they invited 60 volunteers - men and women between the ages of 30 and 60, of average income, who follow the daily standard water procedures. Each of them had navel swabs taken, which were then subjected to biochemical and genetic analysis.

Based on the results of the study, the scientists concluded that about 2368 different bacteria live in the umbilical fossa of the volunteers. Moreover, more than 1,500 species of them are microorganisms little known to science, usually not found on the human body. But how is this possible? And why didn't these microbes cause any disease in humans?

American epidemiologists have made the assumption that over the course of life, under the influence of the environment and taking into account the fact that human clothing covers the umbilical fossa, all people collect and even multiply bacteria in them. Since there is a connection between the navel, stomach and intestines in a person, these microorganisms do not fully, but exert their influence on these organs. However, it does not harm the body, but on the contrary, as it were, "accustom" the gastrointestinal tract to its toxins, improving its performance and increasing overall immunity. That is, a person's navel is one of the involuntary guardians of his health.
