BIRTH

During birth, several changes occur in the mother´s body. First, the walls of the uterus start to contract. Then, the cervix gets wider to enable the baby to come out of the uterus. Next, the amniotic sac breaks and the contractions push the baby into the vaginal canal.

Little by little, the baby is expelled, headfirst, through the vagina. Once the baby is outsidethe mother´s body, it starts to breathe and the doctor cust the umbilical cord. Finally, the amniotic sac, the placenta and the rest of the umbilical cord are expelled.
