The expulsion or removal of an embryo or fetus from the mother prematurely; this can be done as an artificial procedure, but it often happens naturally when the mother's body expels the embryo/fetus because it has died, has genetic or developmental defects, or because of infection or illness in the mother. Natural abortions are typically called "miscarriages". Medically-induced abortions, which can be completed with surgery or with hormone drugs, are done because the embryo/fetus is unwanted, deformed, not likely to live, or endangers the mother's life or health.
