The reproductive system is made up of a uterus (a muscular pear-shaped organ where a baby develops and grows which sits inside the pelvis), the ovaries (two oval shaped organs containing eggs located either side of the uterus connecting to the fallopian tubes), fallopian tubes (the tubes which connect the ovaries to the uterus -once a month, one or sometimes more of these eggs travel down one of these tubes), the cervix (the lower part of the uterus which connects to the vagina) and the vagina (the opening to the pelvis which connects to the uterus). The vulva is the name given for what we see on the outside.

 

These delicate internal and external organs, structures and functions work together with hormones which signal messages to the body, causing the lining of the uterus to build up, getting it ready to release an egg in monthly cycles.These eggs then come together with sperm where they fertilise and form into a baby. If the egg is not fertilised, the lining of the uterus breaks down and leaves the body (bleeds), this is called a period and the same thing happens each month.
