I see that the mesoderm creates the respiratory system but on some tests I got that the endoderm creates it and I also notices it develops the epithelial lining.. I just dont know which I would pick if I saw that question on an exam.. Thanks!

Endoderm = lungs, liver, thymus, thyroid, parathyroid, epithelial lining of most organs

But what about mesoderm? some sources say it creates portions of the respiratory system

Endoderm is mostly responsible for the creation of respiratory system. Mesoderm protects coeloms, which can protect the developing organs such as heart and lungs.
So, the correct answer should always be Endoderm.
