Question

during prenatal development, what tissue will become the digestive system?
a. the mesoderm
b. the ectoderm
c. the endoderm
d. the germ disc

Explanation:

During prenatal development, the three primary germ layers (ectoderm, mesoderm, endoderm) give rise to different body structures. The endoderm is the innermost germ layer. It is responsible for forming the epithelial lining of the digestive tract, respiratory tract, and associated organs (such as the liver and pancreas). The mesoderm forms connective tissues, muscles, etc. The ectoderm forms the nervous system, skin, etc. The germ disc is an early embryonic structure from which the three germ layers develop.

Answer:

C. the endoderm
