An acoelomate is defined as an animal that does not possess a body cavity. Unlike coelomates (eucoelomates), animals with a true body cavity, acoelomates lack a fluid-filled cavity between the body wall and digestive tract. Acoelomates have a triplobastic body plan, meaning that their tissues and organs develop from three primary embryonic cell (germ cell) layers. These tissue layers are the endoderm(endo-, -derm) or innermost layer, mesoderm (meso-, -derm) or middle layer, and the ectoderm (ecto-, -derm) or outer layer. Different tissues and organs develop in these three layers. In humans, for example, the epithelial lining that covers internal organs and body cavities is derived from the endoderm. Muscle tissue and connective tissues such as bone, blood, blood vessels, and lymphatic tissue are formed from mesoderm. Urinary and genital organs including the kidneys and gonads are also formed from mesoderm. Epidermis, nervous tissue, and specialized sense organs (eyes, ears, ect.) develop from the ectoderm.
