Karten in diesem Stapel (12)
- 1Roles-Produce female gametes, Ovum (Ova as plural)
-Receive male gametes (spermatozoa) for fertilisation
-Provides 'site' for fertilisation & for development of zygote - 2ZygoteCell that forms when a sperm fertilises an egg
- 3Ectopic pregnancyWhen fertilised ovum is implanted in fallopian tube instead of travelling through the tube & implanting in the uterus
- 4Female gametes (Ova)-Larger than male gametes (sperm)
-Doesn't move, but has large food store
-Produced once monthly by the two ovaries
-Ovum travels along oviduct/Fallopian tube towards the uterus - 5Fertilisation-Ovum travels along oviduct/Fallopian tube towards the uterus
-Ovum fertilises into a zygote whilst in oviduct/fallopian tube & implants in uterus

- 7Behaviour (during puberty)Girls become more maternal (motherly) & attracted to boys
- 8Pituitary gland-Produces hormones which effect other endocrine organs
-One pituitary hormone stimulates ovaries to produce oestrogen - 9EndocrineGlands which secrete hormones or other products directly into the blood
- 10Oestrogen-Circulates in blood & stimulates secondary sex characteristics (characteristics that appear during puberty)
-Stops FSH being produced so that only one egg matures in a cycle
-Stimulates the pituitary gland to release the hormone LH - 11Secondary sex characteristics-Breasts develop & increase in size
-Nipples become larger
-Vagina increases in size

-Hair develops in pubic region & under armpits - 12Puberty can be delayed in......Extremely muscular girls (e.g. gymnasts)
