coelomával

Coelomával is a term sometimes used to refer to the coelom, which is the internal body cavity found in many animals, including vertebrates, mollusks, and arthropods. This fluid-filled space is located between the digestive tract and the outer body wall. The coelom plays a crucial role in the development, support, and function of various organs. It provides a space for the organs to develop and expand, acts as a hydrostatic skeleton for movement and shape maintenance, and facilitates the circulation of nutrients and waste products.

The presence and nature of the coelom are key characteristics used in animal classification. Animals possessing a true coelom, where the cavity is entirely lined by mesoderm, are known as coelomates. This lining, the peritoneum, also encloses the organs within the coelom. In contrast, animals without a true coelom are acoelomates or pseudocoelomates, depending on the specific arrangement of their internal body cavities. The development of the coelom is a significant evolutionary advancement, contributing to the complexity and diversity of animal life.
