The dedicated 3D model depicts the human fetus at week 30, weighing roughly 1.3 kg, with lanugo beginning to disappear and the bone marrow now serving as the main site of red blood cell production. It illustrates the increasing folding of the cerebral cortex into gyri and sulci, which greatly expands the surface area of the developing brain. As space in the uterus becomes more limited, the fetus gradually begins to settle into its final position, making the model a useful reference for explaining fetal presentation in the weeks leading up to birth.
