Our gonats are formed from the mesoderm. So in female individuals, the ovaries and males, the testes are formed from the mesoderm layer. Now finally, let's move on to our andoderm germ layer. The endoderm germ layer basically consists of the innermost portions of our body and that includes or the majority of the epithelial layer of our body. So recall that the epithelial layer of the mouth and the amus is formed from the actoderm but the rest of our digestive tract and the rest of our digestive system is formed from the endoderm. So the epithelium of the stomach, the small and large intestine are all formed from the endoderm.
