In human umbilical cord there are two umbilical arteries and one umbilical vein. The umbilical cord, which connects your baby to the placenta, contains three vessels: two arteries, which carry blood from the baby to the placenta, and one vein, which carries blood back to the baby.
- The vein carries oxygen and nutrients from the placenta (which connects to the mother’s blood supply) to the baby.
- The two arteries transport waste from the baby to the placenta (where waste is transferred to the mother’s blood and disposed of by her kidneys)
