The foetus is the stage of human development between an embryo (at around 8 weeks) up to when the baby is born.

The umbilical cord joins the placenta to the foetus. It carries the nutrients and oxygen needed from the mother.

Waves of muscle contractions in the uterus wall during childbirth push the baby down through the vagina.

The placenta is an organ that is attached to the uterus wall; it provides the foetus with oxygen and nutrients from the mother's blood.

The amniotic sac surrounds the foetus and contains fluid which protects it.
