===Placental Expulsion===

Expulsion of foetal membranes quickly follows expulsion of the foetus.  After the birth of the young, regular abdominal contractions largely cease, but myometrial contractions persist. They are of decreased amplitude, but become more frequent and less regular. This is important for dehiscence and expulsion of foetal membranes.  Waves of contractions from uterus to the cervix persist.
