The endoderm layer contributes to the formation of the gut during embryonic development. The endoderm gives rise to the lining of the digestive tract, as well as organs such as the liver, pancreas, and lungs. The mesoderm and ectoderm layers also contribute to the formation of other organs and tissues, but not specifically the gut.
