Human Fetus/ Stages of fetal development

During fetal development, a fertilized egg progresses through the embryonic period, fetal period, and final stages leading up to birth. In the embryonic period, major organs and body systems form. The fetal period involves growth, refinement of features, and organ maturation. In the final stages, the fetus prepares for birth, with organ adjustments and positioning. The fetus receives oxygen and nutrients through the placenta and umbilical cord.
