How can the conflict between Rh-negative mother and Rh-positive fetus be explained?

A Rh-negative mother does not have some proteins in the blood, and the fetus may have them. This happens when the fetus inherits an Rh-positive factor from the father. The mother’s body understands that something is wrong, since a foreign protein gets into her body, since it is released during the life of the fetus. The production of antibodies and the attack of the fetus begins. The fetus may die. This has happened before. But in our time, thanks to advanced medicine, it is possible with the help of medicines to end the conflict of organisms.

One of the components of a person's success in our time is receiving modern high-quality education, mastering the knowledge, skills and abilities necessary for life in society. A person today needs to study almost all his life, mastering everything new and new, acquiring the necessary professional qualities.
