Hemolytic Disease of the Newborn (HDN) typically occurs when an Rh-negative mother carries an Rh-positive fetus. In this scenario, if the mother is Rh-negative and the fetus inherits the Rh-positive factor from the father, the mother's immune system may produce antibodies against the fetus's Rh-positive red blood cells, leading to HDN. Therefore, for HDN to occur, the mother must be Rh-negative and the fetus must be Rh-positive.

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.
Where do direct blood and nerve connections between mother and embryo occur?
Direct blood and nerve connections between mother and embryo occur in the placenta. The placenta is an organ that develops during pregnancy and allows for the exchange of nutrients, oxygen, and waste products between the mother and the developing fetus. Nerves from both the mother and fetus also traverse through the placenta to facilitate communication between the two.
What changes occur in blood volume during pregnancy and how does it impact the health of the mother and the developing fetus?
During pregnancy, blood volume increases significantly to support the growing fetus. This increase in blood volume can lead to changes in blood pressure and circulation. It is important for the mother's health to ensure proper blood flow to the placenta and fetus. Inadequate blood volume can result in complications such as pre-eclampsia or poor fetal growth. Monitoring blood volume and managing any related issues is crucial for the health of both the mother and the developing fetus.
If your blood type is O plus can another blood type male empregnate you?
yes -- the real concern is the rh fator of mother/father/fetus and that is for the fetus' protection.
Where does oxygenation of fetal blood occur?
Oxygenation occurs in the placenta. After this blood then returns to the fetus via the umbilical vein.
What are arteriovenous malformations?
Arteriovenous malformations (AVMs) are blood vessel defects that occur before birth when the fetus is growing in the uterus (prenatal development). The blood vessels appear as a tangled mass of arteries and veins.
Why does erythroblastosis fetalis occur with a second pregnancy and normally not the first pregnancy?
The mother is exposed to fetal blood during childbirth or abortion. The Rh+ proteins on the surface of fetal erythocytes can trigger an immune response in the mother. This creates antibodies in the mother and memory lymphocytes that are able to create more antibodies. In the second pregnancy with a fetus with Rh factor, the antibodies in maternal blood can cross the placenta to the fetus and attack the fetus's erythocytes to cause erythroblastosis fetalis. The maternal blood in the first pregnancy does not contain such antibodies to cause the problem because the mother has never been exposed to the Rh factor until the time of first childbirth with the antigen.
When does a human fetus start to produce insulin?
I am actually having the exact situation occur! Apparently, the fetus can be provoked into creating insulin, which affects both the fetus and the mother, as early as 11 weeks gestation. This is also made more apparent in a diabetic mother, as compared to one who is not.
Does The placenta begins absorbing nutrients and oxygen from the mother's body?
Yes, the placenta is responsible for transferring nutrients and oxygen from the mother's bloodstream to the developing fetus. It acts as a barrier that allows for this exchange to occur while also filtering out waste products from the fetus back into the mother's circulation.
Why don't periods occur as normal after an egg is fertilised?
The blood is now being stored and directed to the new developing fetus.
What problems can occur to a fetus when the mother smokes while she is pregnant?
There are many side effects best way to find a bunch is by doing a web search for the answer.
Where does the development of fetus occur?
in the uterus.
