Chicken embryo second stage

This 3D model shows that Chicken embryo grows and develops rapidly. Thus, as one can see looking at the chicken embryo second stage 3D model, the blood islands begin linking and form a vascular system, while the heart is being formed elsewhere. Then the 3D chicken embryo second stage shows some more. The other internal organs continue to develop. And quite soon the 3D chicken embryo has all organs needed to sustain life after hatching, and most of the embryo's parts can be identified.
