Solution
The cells that migrate through the primitive streak into the interior of the embryo in birds become the Endoderm or Mesoderm. These are two of the three primary germ layers in the very early embryo. The endoderm is the innermost layer that forms the lining of the digestive tract and the respiratory system. The mesoderm forms several parts of the body including muscles, bones, and blood vessels.
