The dedicated 3D model depicts the human fetus at week 24, weighing roughly 600 g, with increasingly defined creases on the palms and soles and an inner ear that now contributes to the sense of balance. It highlights the transition of the lungs to the saccular stage, when terminal air sacs form and surfactant production starts, a key requirement for breathing after birth. Clinically, this week falls within the window for antenatal corticosteroids in threatened preterm delivery and for gestational diabetes screening between weeks 24 and 28.
