Eric
1.Ovaries
- have several graafian follicles that develop and burst open to release/produce mature ova
- secretes sex hormones)oestrogen) which initiate/control development of secondary sexual
characteristics
- produce hormones oestrogen and progesterone which prepare the uterus for implantation
and subsequent nourishment of the embryo
2.Oviducts (fallopian tube)
- are thin narrow and tubular to increase flowing speed of semen containing sperms
- are funnel shaped on the end next to ovary which enables them to receive the ovum
- their lining contains cilia which propel the ovum towards the uterus
- has peristaltic muscles that enable movement of zygote/ovum to the uterus for
implantation
- is fairly long to increase surface area for fertilization
3.Uterus
- is muscular for protection of developing embryo
- has elastic wall that allows growth and development of foetus/embryo
- has a highly vascularised endometrium that provides nutrients/gaseous exchange to
developing embryo
4.Cervix
- has valves that close the lower end of the uterus to ensure continued pregnancy during
gestation period
- is capable of dilating
- has narrow entrance/neck-like entrance to uterus that enables quick swimming of sperms
to uterus
- has suction mechanism that draws up/pulls sperms into uterus
- has a “W” shape that fits well with the glands of the penis to ensure sperms are deposited
at the right point
5.Vagina
- is elastic and muscular to enable good accommodation or penetration of the penis thus
proper deposition of sperms and for easy parturition
- allows menstrual flow
- has sensitive labial walls which secrete/produce lubricating substances that
ensure/enable/facilitate good coition
- capable of considerable enlargement, due to elastic muscles, to accommodate baby
during parturition
6.Clitoris
- has sensitive cells for orgasm
