Question

Quizplus · Accepted Answer

The embryonic digestive system is formed from cells in the endoderm layer of the embryo. This layer gives rise to the lining of the gut, as well as organs such as the liver and pancreas. The mesoderm layer gives rise to muscles and connective tissue, while the ectoderm layer gives rise to skin and nervous tissue. The placenta layer is not involved in forming the digestive system of the embryo.
