I'm pretty sure during the first pregnancy it only begins to build us antibodies against the positive rh, however, in the second pregnancy, the mother's body already has a stockpile of antibodies to go after it.
The embryo is fed the mother's blood, so the immune system doesn't attack it. There may be another reason, too. However, sometimes it does, which results in a miscarriage. Note that not all miscarriages are from that, though.
The pregnancy hormone human chorionic gonadotropin, hCG, protects the baby from the mother's immune system.
what organs make up the immune system
Antigen is a component of the immune system. It can trigger an immune response in the body by interacting with antibodies or immune cells.
The specific defense system is also known as the acquired immune system.
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)

The mother's immune system.
The mother's milk contains the antibodies to diseases that she has suffered from since she was born. She passes them onto the baby in her milk, and the baby's immune system creates its own antibodies to protect it.
The embryo is fed the mother's blood, so the immune system doesn't attack it. There may be another reason, too. However, sometimes it does, which results in a miscarriage. Note that not all miscarriages are from that, though.
Antibodies in the immune system system of the mother are given to the child in her milk. Also, the act of nursing helps the mother's uterus return to it's normal size.
The pregnancy hormone human chorionic gonadotropin, hCG, protects the baby from the mother's immune system.
your immune system and your White blood cells produce antibodies
In a healthy person, this would be right after birth, when you're still relying on the antibodies from your mother. However, the immune system can be weakened by a variety of problems, these include AIDS, certain chronic inflections, etc. Old age also weakens the immune system.
The disorder is caused by incompatibility between a mother's blood and her unborn baby's blood. Because of the incompatibility, the mother's immune system may launch an immune response against the baby's red blood cells. As a.
