The dedicated 3D model depicts the human fetus at week 21, a stage of steady weight gain in which the limbs reach more balanced proportions and movements become more frequent and coordinated. It illustrates the maturing digestive tract, which absorbs water and certain dissolved substances from swallowed amniotic fluid, and the growing role of the bone marrow in blood cell production alongside the liver and spleen. The model supports discussion of mid-trimester fetal assessment, including detailed evaluation of the four heart chambers and outflow tracts during the anatomy scan.
