Facts on Fetal Development

The National Geographic Video on Human Development Inside the Womb, shows a unique human being from the moment of conception.   The medical terms of zygote, embryo and fetus are all words used to describe stages of human development, much like toddler, adolescent, teen, and adult, but we are all human beings.

The Endowment for Human Development provides an overview of Fetal Development at each stage of pregnancy, from the moment of conception. 

You can see what the human being looks like at each stage of development:
Human Embryo at 6-8 weeks
Human Embryo at 8-10 weeks
Human Embryo at 10-12 weeks
Human Fetus at 3-6 months
