Growth is faster during the period than any other period in human life. The germinal stage (2 weeks), zygote moves to uterine wall. The embryonic stage (2 weeks to 2 months), vital organs begin to form, also fingers and toes. The fetal stage (2 months to birth), now things continue to grow and eventually begin to function. Teratogens are any external agents, such as drugs or viruses, that can harm an embryo or fetus. Fetal alcohol syndrome: can cause birth defects in babies, small head, heart defects. Certain maternal illnesses can affect the baby, as well as malnutrition.
