Birth

• Amniotic acid sacs:

  • The amniotic acid sac surrounding the fetus breaks and the amniotic fluid leaves through the vagina.
  • This is often known as 'waters breaking'.
• Muscles contraction starts:

  • The muscular walls of the uterus contract repeatedly, preparing to push the baby out.
• Cervix dilates:

  • The cervix (the opening at the bottom of the uterus) gets wider so the baby is able to pass through.
• The baby is born through the vagina, with a head, a body, and four limbs.
• Umbilical cord cut:

  • The baby is still attached to the mother by the umbilical cord when it is born, so it is cut and tied.
  • The remnants of the umbilical chord will eventually fall off the baby, leaving behind a belly button.
• Afterbirth delivered

  • After the baby is born, the placenta is delivered through the vagina.
