umbilical cord
This condition is called Placenta Previa. With placenta previa, the placenta grows on the lower part of the uterus partially or totally covering the opening of the cervix. The placenta should form at the top of the uterus, above the baby. With a normal pregnancy, the baby would be born first, then the placenta. With placenta previa, the placenta would be delivered first. Women with placenta previa require a c-section because as soon as the umbilical cord comes into contact with oxygen, the baby will automatically breathe with his lungs. Delivering the placenta first puts the baby at risk of suffocation in the womb.
The placenta is some times called the 'after birth' as it is expelled from the uterus after the baby is born.
