Solution
A cycle of uterine contractions followed by labour pains, dilation of the cervix and the vagina slowly pushes the fetus out of the uterus. The uterine contractions are initiated by decreased progesterone secretion and the secretion of oxytocin hormone by the pituitary gland. After the child's delivery, the placenta is expelled out.
