I have down that the endoderm is responsible for epithelial lining of the digestive system and respiratory tract (including lungs)
I also have down that the mesoderm is responsible for portions of the digestive system and respiratory system.
Am I right or wrong here? And is there something more specific I'm missing? Thanks!

you are right. I would just memorize ectoderm and endoderm, then mesoderm is everything else.

Thanks Bob!

I'm wondering parts of the respiratory system you're attributing to the mesoderm if the ectoderm develops into the lungs. I think you might have meant circulatory system = mesoderm?

I think this might be an area of overlap. Thats why I posted the question, I was kinda confused. while the ectoderm develops into the lungs, the mesoderm also contributes to the respiratory system, but I don't know what exactly. The circulatory system is definitely the mesoderm, however.
