Key Points: The Female Reproductive System
- The female reproductive system includes a pair of ovaries, oviducts (fallopian tubes), a uterus, a vagina, and Bartholin’s glands.
- All reproductive organs are located inside the abdominal cavity.
- Ovaries release one ovum (egg) monthly after puberty, alternating between each ovary.
- The egg enters the oviduct through its funnel-shaped end and is pushed towards the uterus by cilia.
- Fertilisation usually occurs in the oviduct; the zygote implants in the uterus lining if formed.
- The placenta connects the embryo to the mother for nutrient and waste exchange until birth.
