The umbilical cord is a flexible tube that connects a developing fetus to the placenta in the mother's womb. It serves as a lifeline, providing essential nutrients and oxygen from the mother to the fetus while also removing waste products. The cord typically measures about 50 to 60 centimeters in length and contains two arteries and one vein. After birth, the umbilical cord is clamped and cut, separating the baby from the placenta. The remaining stump usually falls off within a few weeks, leaving behind the baby's belly button, also known as the navel. Proper care of the stump is important to prevent infection.
