Occasionally, during pregnancy, the placenta can separate from the uterus. This causes a disruption in development and sometimes death of the fetus. Harm to the developing fetus might occur because the placenta

• transfers oxygen and nutrients to the fetal blood

• sends maternal blood into the fetus

• supplies milk for the fetus

• breaks down wastes of the fetus
