Acoelomates are found in the kingdom animalia and the phylum Platyhelminthes. Commonly known as flatworms these invertebrate animals are on segmented worms with bilateral symmetry.
An acoelomate is an animal that does not possesses a body cavity. Unlike coelomates animals with the true body cavity, acolemstes lack of fluid filled cavity between the body wall and digestive tract. Acoelmates have what triploblastic body plan meaning that there tissues and organs develop from three primary embryonic cell layers.
These tissues layers are the endoderm or in a most layer, mesoderm or middle layer and the ectoderm or outer layer. Different tissues and organs develop in these three layers. In humans, for example, the epithelial lining that covers the 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.
In addition to not having a body cavity acoelmates have simple forms and lakh highly developed organ system. For example, acoelmates lakh a cardiovascular system and respiratory system and must relay on diffusion across their flat thin bodies for gas exchange. Acoelmates commonly processes or simple digestive tract, nervous system and excretory system.
They have sense organs for detecting light and food sources as well as specialised to self and tubulls for eliminating waste. Acoelmates commonly have a single orifice that serve as both an inlet for food and an exit point for undigested waste. They have a defined hydrogen and display bilateral symmetry which means they can be divided into two equal left and right halves.
