Our belly buttons are perhaps the only marks left behind by the umbilical cord. The umbilical cord is the way babies receive nourishment form their mothers before they are born.
After giving birth, the umbilical cord is cut, and the remaining part dries and falls off in about ten days, forming the belly button. But what is the function of the belly button in the human body? Several studies have analyzed its importance and function. Here are a few interesting facts on them:
–Belly buttons changes during pregnancy. According to specialists from the University Hospitals of Cleveland, due to the expansion of the abdomen, the belly button changes its appearance during pregnancy and sticks completely out. After pregnancy, however, it changes back to its normal appearance.
–Phobia. “Omphalophobia” occurs when someone has a fear of looking at or touching another person’s belly button. Some of the most common symptoms that occur with this phobia are irritability, nausea, dizziness, vomiting and impotency.
–Function. The belly button has an important function during pregnancy as it is responsible for providing food and oxygen to the fetus. After birth, however, it remains a simple mark on the body.
–Missing belly buttons. Some people do not have this birthmark. Specialists explain that the belly button can be removed as the result of a surgical intervention to correct some type of congenital problem, a hernia or a malformation in the stomach.
–Nesting site for bacteria. According to the journal Scientific American, the belly button is home to more than 2,300 types of bacteria, only eight of which are found in more than 70% of people. It is important to wash and dry the belly button well to reduce infection, fungus or bacteria that can pose health risks.
