Human female reproductive system
If the event that egg is not fertilised, the egg lives for about one day. The uterus prepares itself every month to receive a fertilised egg since the ovary releases one egg every month.
As the implantation does not take place the thick lining is no longer required, thus the lining slowly breaks and comes out through the vagina as blood and mucous. This cycle takes place roughly every month and is known as menstruation. It usually lasts for about two to eight days.
