The dead fetus will start to decompose like everything else that is dead and if not removed you will get a serious infection, blood poisoning and become sterile and can even die.
Immune system in a fetus is not well developed. And as such it is less likely and very less harmful for the mother to have damage from antibody from the fetus. Never the less this is possible.
The mother's immune system.
A fetus will start producing IgM antibodies about 20 weeks into the pregnancy. The only antibody the fetus receives from it's mother is IgG which the baby will not start producing on its own until a few months after birth.
Pregnancy
When Rh negative mother carries Rh positive fetus, mother's immune system will not react because most of the time , during the first pregnancy ,fetomaternal blood will not mix. This will happen at the time of parturition and when mother's immune system detects Rh + , it starts producing antibodies and for this it takes at least 3 week and this will have memory. So in her second pregnancy if in case fetomaternal blood are encountered, mothers immune system start destroying the blood cells of the fetus. This case is known as ErythroBlastosis Foetalis or Hemolytic Disease in new born (HDN)
As of yet, the purpose of the appendix in the human body is not known. It is simply there and is often removed. Anyhow, appendix do play role in fetal development and adult.In fetus appendix act as a endocrine organ and in adult they help our body immune system to combat against microbes as it 'train' our immune system by exposing antigens to lymphoid cells in order to produce antibody.
no when Rh negative blood from the fetus interacts with Rh+ blood of the mother there will be no antibodies produced due to absence of antigen on the Rh- blood cells and when Rh positive is mixed with Rh negative blood of fetus no response is produced due to the fact that the fetus has an underdeveloped immune system
No. It can cause damage to the fetus but not abort.
The fetus doesn't necessarily fight off diseases. The mom's immune system fights off certain things. Also, some diseases don't cross over into the baby so depending on what it is, the baby isn't at risk until possibly birth.
No. It can cause damage to the fetus but not abort.
Congenital immunodeficiency is caused by genetic defects, which generally occur while the fetus is developing in the womb. These defects affect the development and/or function of one or more of the components of the immune system.
Yes, this means the fetus is clean. Your blood is his blood. If you have drugs in your system then so will he. You can be prosecuted for drugs in your infant's system.
