what is the part of the unborn baby attached to the mother called
Placental abruption. Placental abruption is a condition where a part of the placenta separates from the uterus during pregnancy. There are many blood vessels within the placenta that transfer nutrients from the mother to the unborn baby. If the placenta detaches during pregnancy, these blood vessels break, and thus there is bleeding. The larger the area that detaches, the more bleeding there is.
