Unit 5 Task 9 – The reproductive system
In the human reproductive process, two kinds of sex cells are involved. The male gamete, or sperm, and the female gamete, the egg or ovum, meet in the female's reproductive system. http://www.nhs.uk/news/2010/01January/PublishingImages/P632053-Coloured_SEM_of_egg_cell_in_secondary_follicle-SPL.jpgWhen the sperm fertilizes, or meets, the egg, this fertilized egg is called the zygote. The zygote goes through a process of becoming an embryo and developing into a foetus. The female reproductive system enables a woman to:
produce eggs (ova) ------------------------------------------------------------>>> have sexual intercourse
protect and nourish the fertilized egg until it is fully developed give birth
Both the male and female reproductive systems are essential for reproduction. The female needs a male to fertilize her egg, even though it is she who carries offspring through pregnancy and childbirth. Unlike the male, the human female has a reproductive system located entirely in the pelvis. The external part of the female reproductive organs is called the vulva, which means covering. Located between the legs, the vulva covers the opening to the vagina and other reproductive organs located inside the body. The uterus is shaped like an upside-down pear, with a thick lining and muscular walls – it has some of the strongest muscles in the female human body! There are two fallopian tubes, each attached to a side of the uterus. The fallopian tubes are about 4 inches (10 centimetres) long and about as wide as a piece of spaghetti. The ovaries are also part of the endocrine system because they produce female sex hormones such as estragon and progesterone.
