In the first 6 days of the menstrual cycle the uterine wall leaves through the vagina. This is often called a 'period'. | On day 7 an ovum begins to mature and the uterine wall starts to build back up again. | The uterine wall continues to build up. | The uterine wall continues to build up. |
The uterine wall continues to build up. | The ovum is released from the ovary. | The ovum travels down the oviduct. | If the ovum is not fertilised the uterine wall breaks down. |
