The placenta is the container that keeps the baby isolated from the mother. The fetal blood flows through the baby, out the umbilical cord to the placenta and no further. The placental membrane separates maternal blood from fetal blood.Oxygen and nutrients in the maternal blood in the intervillous spaces diffuse through the walls of the villi and enter the fetal capillaries.he fetal blood flows through the baby, out the umbilical cord to the placenta and no further.

Usually a mother and babyâs blood do not mix while the baby is in the womb. The motherâs blood runs alongside the placenta, and the nutrients needed by the baby are absorbed and transferred to him/her. A membrane separates babyâs blood and motherâs blood â all the babyâs blood is contained within the baby and placenta. Sometimes a traumatic event like a car accident, a CVS or amniocentisis procedure, etc. can cause the blood to mix. It also sometimes mixes during childbirth.
