True, in the placenta the blood of the mother and the fetus is separated so that an exchange of gases and nutrients can occur.
How does the placenta work?
The link between the mother and the embryo is the placenta which is a highly specialized pregnancy organ. This organ supports normal growth and development from embryo to fetus.
The placenta has many functions, one of which is providing oxygen to the fetus. The fetus gets nutrients and oxygen from the mother through the placenta which is attached to the umbilical cord. Within the placenta, the blood of the mother and fetus each flows through vessels that are close to each other. Even though they are close together, the blood of the mother and the fetus does not mix. When the mother's blood is close to the fetal blood, there is a locking of oxygen and nutrients from the mother's blood to the fetal blood. Usually, the placenta attaches to the uterine wall of the mother. These organs are usually attached to the top, side, front, or back of the uterus.
