We've reached the grand finale of our four part series on human reproduction: BABIES! Today Hank walks you through the stages of pregnancy, beginning with how a zygote develops into blastomeres to a morula to a blastocyst and finally to an embryo and a fetus. He also explains some of the amazing anatomical changes that take place in the mother, and the hormonal sequence of events that lead to labor.
