Introduction:

The formation of all the structures and organs of the body takes place during embryonic and fetal life. The three layers of the embryo that are endoderm, ectoderm, and mesoderm form all the structures of the body. The primitive that originates from the endoderm gives rise to the foregut, the midgut, and the hindgut. Later on, all the structures of the alimentary originates from these layers.
