Pigs, like other mammals, have three primary tissue layers: the ectoderm, mesoderm, and endoderm. These layers give rise to various organs and structures during development. The ectoderm forms the skin and nervous system, the mesoderm develops into muscles, bones, and the circulatory system, while the endoderm becomes the lining of the digestive and respiratory tracts.
