4 Weeks 4 Weeks A water-tight sac forms around the growing fertilized egg. This sac gradually fills with fluid so it can help cushion the growing embryo.

Days 1-5 Menstruation Menstruation occurs and the lining of the uterus, with a small amount of blood, leaves the body. At this time another egg is maturing.

Development Egg gamete leaves ovary Egg gamete leaves ovary Travels through fallopian tube where it can be fertilized Travels through fallopian tube where it can be fertilized This new life continues to multiply as it travels to uterus This new life continues to multiply as it travels to uterus Once in the uterus it implants in the lining forming the umbilical cord Once in the uterus it implants in the lining forming the umbilical cord This will be its life support while developing in the womb This will be its life support while developing in the womb

Humanistic Reasoning I am the only one that matters I am the only one that matters There is no God, we are all a matter of chance, developed from animals, and not human until we are born There is no God, we are all a matter of chance, developed from animals, and not human until we are born Justify abortion because it is not human Justify abortion because it is not human Once the baby is born it is protected by law Once the baby is born it is protected by law Up until the minute is born it is a thing that can be killed Up until the minute is born it is a thing that can be killed
