Verified step by step guidance

Understand the concept of germ layers: In embryonic development, three primary germ layers form, which are the ectoderm, mesoderm, and endoderm. Each of these layers gives rise to different tissues and organs in the body.

Identify the function of each germ layer: The ectoderm forms structures such as the skin and nervous system. The mesoderm gives rise to muscles, bones, and the circulatory system. The endoderm forms the lining of internal organs.

Focus on the endoderm: The endoderm is the innermost germ layer and is responsible for forming the lining of the digestive and respiratory tracts.

Relate the endoderm to the digestive tract: Since the endoderm forms the lining of internal organs, it specifically gives rise to the epithelial lining of the digestive tract.

Conclude that the endoderm is the correct answer: Based on the functions of the germ layers, the endoderm is responsible for the development of the lining of the digestive tract.
