Tues: What is the role of the umbilical cord? Placenta?

  • The placenta provides all the oxygen, water and nutrients the baby needs to grow in the uterus
  • transmits fetal waste and carbon dioxide from the baby to the mother’s system for excretion
  • produces hCG (human chorionic gonadotropin), the hormone considered necessary to establish a healthy pregnancy
  • placenta is attached to the fetus through the umbilical cord
    • It contains one vein, carrying oxygenated blood from the placenta to the baby, and two arteries, bringing deoxygenated blood from the baby to the placenta.
