The fetus is nourished by the yolk sac during the first 7 weeks of development and by the placenta from week 8 through to birth. The yolk sac provides initial nourishment, while the placenta takes over essential functions as the pregnancy progresses. This transition allows for more efficient nutrient exchange between the mother and the developing fetus.
