list and describe the developmental stages of pregnancy
Fertilization (Day 0): An egg and sperm unite and produce a zygote.
Blastogenic stage (Day 1 to 14): A period of rapid cell division Day 14: An embryo is formed.
Embryonic stage (Week 2 to 8): The organ system develops.Week 5: The heart begins to beat. Week 8:
The embryo is now known as a fetus.
End of first trimester: Most organs are formed, and the fetus can move.
