Reproductive organs
Girls have two ovaries that hold thousands of tiny eggs. These eggs would have been inside you when you were still developing as a baby inside your mother’s womb. About once a month, one of your ovaries releases an egg that passes into one of the fallopian tubes and onwards towards the uterus. This is called ovulation and is very important because this is the time that an egg can become fertilised and develop into a baby. Before an egg is let go, the uterus creates a rich lining of tissue and blood vessels, which is important to keep a fertilised egg alive. Usually, an egg breaks apart before it reaches the uterus, but if sperm from a boy or man’s penis meets the egg on its way to the uterus, it can fertilise the egg and pregnancy begins when this fertilised egg attaches itself to the lining of the uterus.When the unfertilised egg breaks apart, the lining is no longer needed, so it flows out of the uterus, through the cervix, down the vagina and out of the body. This is the menstrual flow. To protect your clothes from this flow of tissue and blood, you will need to use sanitary pads or tampons. A period can last from 3 to 7 days and the menstrual cycle repeats itself approximately every 28 days until the age of between 45 and 55, with the exception of when becoming pregnant.
