Coelomic fluid, also known as coelomica or coelico, is the fluid found in the coelomium, a section or cavity of the body of some animals. The appearance of the coelomic (rhizome-like system) is associated with increased efficiency and coordination of movements. In modern terminology, there are several definitions of coelomia that take into account different aspects of this intracellular structure, but they are only indirectly related to the content of this article.
The phenomenon of coelomic fluids is truly an amazing phenomenon of life associated with the development of a number of organ systems and tissues. At the same time, the coelomic type of organization of fluid distribution systems (coelomia, coelomic blood circulation) is present in a fairly large number of ancient zoo- and phytoplanktonic forms (ciliates, shell rhizomes, nematodes, certain plant species). It is obvious that coelomission has deep roots in the biogenesis of life. However, within the framework of a scientific approach, we can only talk about certain signs of coelomia.
