Pronunciation: [ˈɛndə͡ʊdˌɜːm] (IPA) 
Endoderm is a term commonly used in biology to describe the innermost layer of cells in an embryo that forms the lining of the digestive and respiratory tracts. This germ cell layer is sometimes referred to as the hypoblast, gastrula or the primitive gut. Other synonyms for endoderm include the visceral layer, the internal germ layer, and the digestive layer. Together with the ectoderm and mesoderm, the endoderm plays an essential role in the embryonic development of all multicellular organisms. Understanding its functions, synonyms, and how it interacts with other cell layers is vital to the study of developmental biology.
