Belly button
Belly Button
The Belly Button (pronunciation: /ˈbeli ˈbʌtn/), also known as the Navel (pronunciation: /ˈneɪvəl/), is a central scar on the abdomen at the attachment site of the Umbilical cord.
Etymology
The term "Belly Button" is derived from Middle English. "Belly" comes from the Old English belg which means bag, and "Button" comes from the Old French bouton which means bud or knob. The term "Navel" comes from the Old English nafela, which is akin to the German Nabel and the Latin umbilicus.
Anatomy
The Belly Button marks the area where the Umbilical cord was once attached. The cord is a conduit between the developing embryo or fetus and the Placenta. The umbilical vein supplies the fetus with oxygenated, nutrient-rich blood from the placenta. Conversely, the umbilical artery carries deoxygenated, nutrient-depleted blood away.
