Respuesta :
The fetus may have Rh-positive blood, inherited from the father, if a Rh-negative woman and a Rh-positive man become pregnant. (Approximately 50% of children with a Rh-positive father and a Rh-negative mother will be Rh-positive.)
What's an Rh Factor?
- Some red blood cells include a protein known as a Rh factor (RBCs). Although most people do, not everyone possesses this protein. They have positive Rh.
- Rh-negativ people are those who don't carry the protein. If it's the mother's first pregnancy, rh incompatibility typically doesn't pose a concern.
- That's because during pregnancy, the mother's blood does not often enter the vascular system.
- The blood of the mother and the baby, however, may mix during delivery.
- In this case, the Rh protein is perceived as an alien substance by the mother's body. It may then start producing antibodies—proteins that serve as defenses in the event that the body is invaded by foreign cells—against the Rh protein.
