The blood is "grown" by the fetus along with the organs and bones. The fetal blood supply is separate from the mother's. The two blood systems interact through the placenta - oxygen and food pass though to the fetal blood from the mother, waste products flow from the fetus to the mother.
No, because if it did the mother's body would reject the baby.
Metabolic wastes.
blood flow from the mother to the fetus
it is the interface between the fetus and the mother's blood supply it acts like a filter - supplying nutrients to the fetus and disposing of waste material from the fetus to the mother all of this without actually mixing the blood of the fetus and the mother
Yes, there is no danger to the fetus is the mother is type A and baby is type B
Blood from the mother is used by the fetus.
From the mother's blood via the placenta.
the placenta
Absolutely YES! Substances of good/bad can be transported from what is inhale by the mother to the fetus by the process of "blood flow from the mother to the fetus" or entering the umbilical cord to the fetus .
Baby gets food and oxygen through the umbilical cord. This umbilical cord is attached to the placenta. This placenta is attached to the uterus. In the placenta blood of the mother comes close to the blood of the fetus. There is transfer of food and oxygen to the blood of fetus from the blood of mother. Carbon bi oxide and waste products of metabolism are transferred to the blood of mother from the blood of fetus.
No. The placenta produces and cleanses the blood for the fetus.
The fetus is connected to its mother by an umbilical cord. The mother's blood carries nutrients through the umbilical cord to the fetus and carries away wastes from the fetus.
Through the blood system
They are transported from the placenta through the umbilical cord to the fetus. The baby takes nutrients and oxygen from the mother's blood, which travel's through the umbilical cord to the baby
