臍帯
After birth, the umbilical cord isn’t needed anymore. So, a healthcare professional clamps and cuts it soon after your baby is born. This leaves behind a short stump. A baby’s umbilical cord stump needs to dry up before it falls off. Most often, the stump falls off 1 to 3 weeks after birth. https://www.mayoclinic.org/healthy-lifestyle/infant-and-toddler-health/in-depth/umbilical-cord/art-20048250
