google is your biggest friend --> try search there, there can be found enough about derivatives of germlayers.

--> remember what is ectoderm and endoderm and mesoderm

--> ectoderm = skin for example

--> endoderm = primitive gut (the lungs are formed out of this structure)

--> mesoderm is divided into four pieces: axial/paraxial intermediar / lateral plate mesoderm

the kidneys are formed out of the intermediar mesoderm for example and the heart out of the lateral plate mesoderm.

Also mesoderm is what separates us from the acoelomate.
