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.

A baby gets all of his food, as well as his oxygen and water, from its motherâs bloodstream. The babyâs waste products (like C02) are disposed of in the motherâs blood stream as well. It is a two-step process.In the placenta, the mothers blood flows in to a network of blood vessels and capillaries.Molecules in the motherâs blood like glucose, proteins, fats, oxygen, etc. flow out of the motherâs blood supply and are absorbed into another network of blood vessels and capillaries containing the babyâs blood supply.The babyâs blood then flows through the umbilical cord back to the baby.utrients are absorbed some through the stomach, and more so through the small intestine. They are broken down into their smallest components, and Mom's blood reaches the baby through the blood vessels in the placenta and umbilical cord.
