Introduction:
When human sperm and egg unite, the event is known as fertilization. After the fertilization process, implantation occurs wherein the embryo gets attached to the uterus lining and with the help of hormones the embryo grows into a full grown human baby. So, the first trimester is characterized by the cleavage, implantation, placentation, and embryogenesis.
