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).

In the mammalian fetus where does fetal blood exchenge carbon dioxide for oxygen?
In the mammalian fetus, the exchange of carbon dioxide for oxygen occurs in the placenta. The placenta is a temporary organ that develops during pregnancy to allow for the transfer of gases, nutrients, and wastes between the maternal and fetal bloodstreams. Oxygen from the mother's blood diffuses into the fetal blood, while carbon dioxide from the fetus diffuses into the mother's blood for elimination.
Why does fetal haemoglobin pick up oxygen at the placenta at partial pressure which causes maternal haemoglobin to release oxygen?
Fetal hemoglobin has a higher affinity for oxygen compared to maternal hemoglobin. This means that at the lower oxygen partial pressures found in the placenta, fetal hemoglobin will bind more oxygen, causing maternal hemoglobin to release its oxygen. This mechanism ensures efficient transfer of oxygen from the mother to the fetus.
What fetal blood vessel has the highest oxygen concentration?
The umbilical vein carries oxygen-rich blood from the placenta to the fetus, making it the fetal blood vessel with the highest oxygen concentration.
What is the fetal circulatory structure that carries blood with the lowest oxygen saturation?
The ductus venosus is the fetal circulatory structure that carries blood with the lowest oxygen saturation. It allows blood from the umbilical vein to bypass the liver and flow directly to the inferior vena cava.
What carries nutrients and oxygen to an embryo from its mother?
The placenta is the organ that carries nutrients and oxygen to an embryo from its mother. It is formed during pregnancy and serves as the interface between the maternal and fetal circulation, allowing for the exchange of gases, nutrients, and waste products.
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.
What is feto-maternal?
Feto-maternal refers to the relationship between the fetus and the mother during pregnancy. It involves the interactions and exchanges that occur between the developing fetus and the mother's body to support fetal growth and development. This relationship is crucial for the health and well-being of both the fetus and the mother.
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
Why is there not enough fetal DNA in my blood?
There may not be enough fetal DNA in your blood due to several factors, including the gestational age of the pregnancy, the maternal-fetal placental dynamics, and individual biological variability. In early pregnancy, the amount of fetal DNA in maternal circulation is lower, and it gradually increases as the pregnancy progresses. Additionally, conditions such as obesity or certain medical conditions can also affect the levels of circulating fetal DNA. If you're concerned about insufficient fetal DNA, consulting with your healthcare provider can help clarify the situation.
What are the differences between the maternal blood entering and leaving the placenta?
Maternal blood entering the placenta is oxygen-poor and nutrient-depleted, carrying carbon dioxide and waste products from the fetus. As blood flows through the placenta, it undergoes gas and nutrient exchange; oxygen and essential nutrients are transferred to the fetal blood, while waste products are transferred to the maternal circulation. The blood leaving the placenta is thus oxygen-rich and nutrient-enriched, ready to nourish the fetus. This efficient exchange is vital for fetal development and growth.
What factors can cause fetal bradycardia during pregnancy?
Fetal bradycardia during pregnancy can be caused by factors such as maternal hypotension, maternal hypothermia, fetal hypoxia, umbilical cord compression, and certain medications.
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.
