No. The placenta produces and cleanses the blood for the fetus.

The mother and baby do not share the same blood circulation during pregnancy. Oxygen and nutrients are transferred from the mother to the baby through the placenta, a temporary organ that develops during pregnancy. The mother's blood and the baby's blood do not mix.
No, digested food does not pass directly from the mother's blood to the baby's blood. Nutrients from the mother's blood are transferred to the baby's blood through the placenta, which acts as a barrier to prevent direct mixing of blood between the mother and the baby.
A baby with erythroblastosis fetalis typically occurs when a mother with Rh-negative blood type is pregnant with a baby who has Rh-positive blood type. If the mother's blood is exposed to the baby's blood during pregnancy or birth, the mother's immune system can produce antibodies that attack the baby's red blood cells, causing severe complications for the baby.
Not necessarily. The blood type of a first born baby can be the same as the mother's, but it can also be different if the baby inherits a different blood type allele from the father. The baby's blood type is determined by a combination of the parents' blood types.
If the father's blood type is O and the mother's blood type is A, the baby could have a blood type of either A or O. The baby will inherit one blood type allele from each parent, so there is a 50% chance of inheriting the A allele from the mother and a 50% chance of inheriting the O allele from the father.
During the embryonic stage, the baby receives its nutrients through the umbilical cord, which is connected to the placenta. The placenta allows for the transfer of oxygen and nutrients from the mother's blood to the developing embryo. This ensures that the baby receives the necessary nourishment for growth and development.
