Science on Instagram: "Fetus development is the process by which a fertilized egg grows into a baby inside the mother’s womb. It begins after the eighth week of pregnancy when the embryo becomes a fetus. During this time, all major organs form and mature — the heart starts beating, limbs grow, and facial features develop.
