Question

Which of these germinal layers give rise to the digestive system, the circulatory system, and the nervous system?. . . . Endoderm, mesoderm, and ectoderm, respectively . . . . Mesoderm, ectoderm, and endoderm, respectively . . . . Ectoderm, endoderm, and mesoderm, respectively .

Answer 1

The correct answer is endoderm, mesoderm, and ectoderm respectively.

Later on, the digestive system rises from the endoderm, mesoderm rises to the circulatory system, and ectoderm differentiates to form the nervous system.

Thus the correct answer is Endoderm, mesoderm, and ectoderm respectively.
