    Flashcards

    Fertilization

    The process where sperm meets egg to create a zygote.

    Menstrual cycle

    A monthly cycle, lasting about 28 days, that prepares the uterus for fertilization.

    Ovaries

    Glands that produce female sex cells (ova/eggs).

    Placenta

    An organ connecting the mother to the fetus, providing oxygen and nutrients.

    Study Notes

    Fertilisation and Embryo Development

    • Fertilisation occurs when sperm and egg cells meet
    • Male sex cells produce sperm
    • Female sex cells produce ova
    • Ovaries produce eggs
    • Eggs travel through the oviduct
    • Eggs are fertilised in the uterus
    • Fertilised egg develops into an embryo
    • Embryo develops into a foetus
    • Pregnancy lasts around 9 months
    • The placenta provides oxygen and nutrients to the developing foetus

    Menstrual Cycle

    • The menstrual cycle is a 28-day cycle
    • The uterine lining sheds, known as menstruation
    • The cycle prepares for a possible pregnancy
    • Ovulation occurs in the middle of the cycle
    • This is when an egg is released from the ovary into the fallopian tube
    • If fertilisation does not occur, the egg is lost

    Pregnancy

    • Pregnancy lasts approximately 9 months
    • Foetal development occurs within the uterus
    • Protection and nutrients are provided to the embryo
    • Placenta provides nutrients to the foetus
    • Amniotic fluid cushions and protects the developing foetus
    • Umbilical cord connects the foetus to the placenta
