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.

Pupils will learn about flower structure, wind and insect pollination, fertilisation, seed and fruit formation and dispersal.

Pupils learned about heredity as the process of organisms passing on genetic material to their offspring during reproduction, and about DNA, genes and chromosomes.

This unit explores human reproduction, covering the structure and function of male and female reproductive systems, the menstrual cycle, gametes, fertilisation, gestation, and birth. It also examines how maternal lifestyle impacts the foetus through the placenta.
