If a cell is fertilized, a baby will eventually grow from it. Fertilization - the joining of a female egg with a male reproductive cell If an egg is fertilized it will travel through the fallopian tube to the uterus The uterus is the organ in the mother’s body where a baby will develop until birth.

Menstruation :

Menstruation - when blood, tissue and the unfertilized egg flow out of the body Also known as a “period”. Most girls can expect to begin this between the ages of 9 and 16.
