Draw a labelled diagram of the human female reproductive system. How does the developing embryo get its nourishment?

1. 1 · Open in one line. The female reproductive system makes eggs and nourishes the developing baby.
2. 2 · Name the organs. Ovaries, oviducts, uterus, cervix and vagina, with one job each.
3. 3 · Fertilisation and implantation. The egg meets a sperm in the oviduct; the zygote divides and implants in the thick lining of the uterus.
4. 4 · Placenta. Villi on the embryo's side and blood spaces on the mother's side; glucose and oxygen pass in, wastes pass out.
5. 5 · Draw the system. [Diagram: ovary, oviduct, uterus, cervix, vagina]
6. 6 · Link to daily life. Pregnant women are advised a nutritious diet and regular check-ups, because the baby's food comes from the mother's blood.
7. 7 · Close in one line. The embryo grows for about nine months, fed through the placenta.

Scoring tip: Write that fertilisation happens in the oviduct, not the uterus; it is a common error.
