Endoderm: (most internal germ layer) gives rise to the lining of the digestive tract and the organs derived from it, such as the liver and lungs of vertebrates.
Mesoderm: (middle germ layer) forms muscle, the skeletal system, and the circulatory system.
Ectoderm: (most exterior germ layer) gives rise to the outer covering and, in some phyla, to the central nervous system.

The three primary germ layers that form during the embryonic development of mollusks are the ectoderm, mesoderm, and endoderm. The ectoderm gives rise to the skin and nervous system, the mesoderm forms muscles and internal organs, while the endoderm forms the digestive tract.
endoderm
The three main types of cells that can form during differentiation are endoderm, mesoderm, and ectoderm. Endoderm gives rise to internal organs such as the gastrointestinal tract. Mesoderm forms tissues like muscle and bone. Ectoderm develops into the nervous system and skin.
The three germ layers of a gastrula are the ectoderm (outer layer), mesoderm (middle layer), and endoderm (inner layer). These layers give rise to different tissues and organs in the developing embryo through a process known as gastrulation.
Prussian embryologist Robert Remak coined the term "endoderm" in 1835. The endoderm is the innermost of the three primary germ layers of an embryo. The endoderm may also be called the hypoblast.

endoderm, mesoderm, then ectoderm
The endoderm of the gastrula turns into internal organs such as the liver and pancreas, and into the lining of some systems.
