Three reasons why fetal blood must not mix with maternal blood?

Number one:
If you are RH- and your baby RH+, and your blood mixes with your baby's, it could become sensitized. Your body could begin producing antibodies to the RH+ blood. If these antibodies get to an unborn baby, they can begin killing off the baby's red blood cells. This is called RH disease. It is rare for it to affect a first baby, but if the mother becomes sensitized and produces antibodies to RH+ blood, it could cause problems for future babies. RH disease is very serious; however, recent medical advances allow 90% of babies with RH disease to survive (March of Dimes).

What is the fetal circulatory structure that carries blood with the lowest oxygen saturation?
Ductus arteriosus
What is a normal fetal oxygen saturation?
60
During which five-week period did the fetal mass increase at the greatest rate?
About weeks 30-35
The direct source of ATP for the development of a fetus is?
The direct source of ATP for the development of a fetus is a series of chemical activities that take place in the mitochondria of fetal cells.
What happens if you do not get enough of folic acid?
Folate deficiency may lead to glossitis, diarrhea, depression, confusion, anemia, and fetal neural tube defects and brain defects (during pregnancy).
What is feto-maternal?
Feto-maternal refers to a fetus and its mother. Fetal-maternal hemorrhage refers to the entry of fetal blood into the maternal circulation before or during delivery.
What blocks maternal recognition of fetal red blood cells?
RhoGAM
What precautions can be taken to prevent fetal exposure to HIV-infection?
Precautions for preventing fetal exposure to HIV-infected maternal blood include avoiding: amniocentesis, fetal scalp blood sampling, premature rupturing of the fetal membranes.
What prenatal tests can detect toxoplasmosis?
Prenatal tests for toxoplasmosis include a blood test for maternal antibodies; testing of the amniotic fluid and fetal blood; and, fetal ultrasound.
Does maternal and fetal blood mix together?
The maternal and fetal circulatory systems are separated by the placental barrier; some molecules (for example nutrients, oxygen, and certain proteins) are able to pass through, but "blood" doesn't. Injuries could result in the blood mixing, but this is a bad thing and is not supposed to happen to any significant degree.
What is a metabolically active organ that develops as an interweaving of fetal and maternal blood vessels embedded in the uterine wall?
placenta
How are maternal to fetal infections passed?
Maternal to fetal infections are transmitted from the mother to her fetus, either across the placenta during fetal development (prenatal) or during labor and passage through the birth canal (perinatal).
What are other names for prenatal surgery?
Fetal surgery, antenatal surgery, or maternal-fetal surgery.
What has helped to reduce maternal-fetal transmission of HIV?
In developed countries widespread HIV testing and anti-retroviral therapy have reduced maternal-fetal transmission dramatically.
Where is the chorion membrane located?
The Chorion is one of the membranes that exists during pregnancy between the developing fetus and it's mother. It allows the transfer of nutrients from the maternal blood to the fetal blood.
What test uses a combination of fetal monitoring maternal reports of fetal movement and the fetal heart rate to determine the health of the baby in utero?
ultasound
How can maternal-to-fetal HSV transmission be prevented?
Prevention of maternal-to-fetal HSV transmission includes abstaining from sexual activity during the last trimester; using a condom; postponing membrane rupture; avoiding a fetal monitor; and, avoiding vacuum or forceps deliveries.
