Quizplus · Accepted Answer

Internal organs, such as the digestive system, respiratory system, liver, and pancreas, develop from the endoderm germ layer during embryonic development. The mesoderm gives rise to structures such as bones, muscles, and kidneys, while the ectoderm forms the skin, nervous system, and sensory organs. The blastoderm is a term that can refer to the entire early embryo or the layer of cells formed after the first few cell divisions.
